I'll second this. It's a pretty great museum. If you're at all interested in Roman stuff taking the train down to Bath for a day is totally worth it. The Roman Baths are great and there is a free walking tour of the city that is good fun if the weather isn't awful. Greenwich is also fun if you want to nerd out about boats and/or the prime meridian.

They tried to turn a pistol into a submachine gun. Those attachments would be necessary to have any semblance of control firing that thing on automatic. The general theory behind things like that is to issue them to troops for whom a rifle would be inconveniently bulky. Generally the stock in a production model would be a folding wire frame deal or double as a holster. The whole idea of issuing subguns sort of fell out of favor with the introduction of assault rifles and their carbine variants.

If you're an infantryman, you'd be carrying around a proper weapon to begin with, but if you were an artilleryman, or a tank crewman, or doing something like that, odds are that your big and heavy gun (if you were ever issued one) would be leaning against the side of a trench or in your tank that is currently on fire (no one is going to waste time grabbing a full sized SMG when climbing out of a burning tank) when the time came to use it. Therefore, it's better to turn a pistol into something that can act as an SMG for a short period of time until immediate danger passes.

However, you're right, the attachments are still pretty bulky, the result is not particularly accurate or reliable, and when you actually have to use one of these things, odds are you won't have time to strap all that extra crap to it before shooting. People in the above category preferred SMGs and carbines with folding stocks to this monstrosity, anyway.

For Berlin:

The lines for the reichstag can be very long so research the best time to get there. There is also a nice memorial to the victims of national socialism nearby and a small memorial outside the reichstag itself to politicians killed by the nazis. After the reichstag the soviet WW2 memorial is a short walk away, inside the tiergarten though the victory column is a bit of a walk from there. The German History museum is also fantastic and a must see.

I know your schedule is very tight but if you happen to be in France for the 29tth or 30th of June OR the 19th or 20th of July the French tank museum in samaur is having a field day where they drive a bunch of tanks around.

If you take archaeological evidence instead of just recorded history, it even extends far beyond 1457 BC. Somewhere between 2191 BC until 2112 BC saw heavy fighting in Mesopotamien: First the southern part of the collapsing early Akkadian empire was overrun by a tribe called the Gutians, then the citystates of Mesopotamia fought them off again.

Then there was the war of Ur against one of its neighbouring citystates: Some trading city (I forgot the name) was sieged and conquered by Ur. I think that was even earlier then the Gutian war.

Edit:
Also apparently Ur used the distraction due to all these Gutians running around and wrecking poo poo to conquer Akkad itself. And some sources apparently say the Gutians weren't fully defeated until 2100 or even 2000 BC.

Well I guess even with the Sumerian obsession with keeping lists it would be a bit too much to demand perfect knowledge of a conflict which happened more then 4100 years ago.

Edit2:
I'm thinking about making an effort post about ancient Mesopotamien wars. There's a book from Hans J. Nissen I want to use as a source, edition from 1999 or 2012 if I can find it in one of our universitary libraries. Since it will take me quite a while (finding the book, reading it, writing a post), feel free to warn me if someone knows that book and thinks it's bad or something. (It's title is Geschichte Altvorderasiens), I almost forgot.)

There are records of wars from about 2500 or so; even if they are mixed up with myth and legend. Gilgamesh, for example, certainly fought the other Sumerian city states and the Elamites, even if he didn't really fight dragons and catoblepas. After him, in the 2400s we start seeing other "praise poems" by kings boasting of their accomplishments. That plus archaeological evidence has shown that the Sumerian states fought each other for hegemony and tribute; for a while Eridu was top dog, then Uruk, then Lagash, and finally Umma before Sargon sweeps down and defeats them all, forming the short-lived Akkadian empire in about 2100.

If I recall, the best records come from Lagash, which has its kings boasting of sacking Umma, and then building a momument overlooking the city to rub it in. Then, of course, about 200 years later, you have the king of Lagash complaining that Umma sacked his city, and tore down the monuments and plundered the temples. Unfortunately, the records aren't terribly clear on where the battles were fought, what tactics were used, how the sieges went down, which is why people tend to think of Megiddo and Kadesh as the earliest battles known.

Yeah, I kind of destroyed my own argument there, since I mentioned how the Sumerians had lists for everything, their wars didn't really go "unrecorded", for truly unrecorded wars we would have to go farther back, but I have a few weeks of reading to do until I understand the matter good enough to talk about it.

About old battles, a battle rather well-known only for a few years now was the siege I mentioned in my post. Hopefully I can find the article again, but since I forgot the trading city Ur conquered and Google is rather nasty if you search for two-letter words like "Ur", welp. That city was apparently quite a surprise because it was thought ancient cities developed mostly around agriculture, so finding a city of the 3rd millenium before common era who entirely developed around trade and manufacturing was quite strange. Also the archaeologists found evidence that the city entered a new golden age under Ur after its conquest. So the siege had a happy end, in a way.

Uh, no. I still remember the name started with a "H". Also the siege saw the heavy use of some fancy Ur-siege weapon. Some sort of spherical ceramic device, hurtled against the city using catapults. The archaeologists found them everywhere in the ruins of that city, apparently they smashed even into buildings from above and the citizens just left them lying around for some reason.

That's everything I remember now, if that helps.

Edit:

I remembered another tidbit from the article: The city was somewhere close to or in a mountaineous region. There was no river or even agricultural usable plains anywhere close. The city only survived on trade.

Anything specific? One common thing about WWII subs that general populace consistently gets wrong is that they were in fact surface vessels with a capacity to become temporarily submerged, not the permanently hidden monsters of the Cold War. Other than that, there's a lot of possible topics pertaining to each national branch.

Even more fascinating in my mind is that there was a notable submarine presence in WWI as well. Obviously the technology at the time was even more restrictive in its ability to stay submerged than in WWII as well. I've always had the impression that in WWI at least their psychological impact was much greater than their material impact but I don't have anything to back that up. If I lived in a time and place where airplanes have only existed for 10ish years, most people in rural America don't have electricity, and the enemy is sinking your ships with ships that go under loving water I'd be terrified.

Can you talk about the changes to submarine tech, doctine, and usage between the two wars?

Also, Das Boot and its kickin rad 80's music should be required viewing for someone interested in WWII submarine warfare.

As it happens, part of the plan for Jutland was that before the Grand Fleet got to the Germans, they would have traveled over a pre-placed submarine line and were supposed to get some dreadnoughts sunk, evening the odds before the real battle. Unluckily, the German fleet was forced by weather to leave port later than was planned and the submarines were within a day of being forced to return to Germany to resupply, and managed to hit precisely 0 British ships.

Sorta the reverse happened before Midway - IIRC the Japanese subs got into position right after the American carriers had sailed by.

The city was called Hamoukar and excavation has been ongoing since 2003. It's ruins are near the outskirts of Akaba, a city in Jordan. (Also at the coast of the Red Sea, so I have no idea why I thought the city would be in the mountains.)

HELL SERPENT
Lipstick Apathy
The two primary weapons of the submarine were always the deck gun and the torpedo in both World Wars. Evolution in technology mostly came in the form of faster subs, more endurance/range, and more destructive/accurate torpedoes.

In World War I, the submarine was still a very new weapon - its modern incarnation was actually invented by an American, and the war started with Britain and France having more and more modern subs than Germany. It's initial use was as scouts or screens for capital ships, and to attack enemy capital ships from stealth. Sinking a battleship or a cruiser without a major engagement was a pretty plum deal.

The Royal Navy under Admiral Jellicoe was very well aware of the threat posed by subs as a means for Germany to sink some RN battleships without a fight and so erode at the margin of advantage in dreadnoughts that they had. This fear was taken very seriously indeed when on Sep 22, 1914, three old RN cruisers, the Aboukir, the Hogue and the Cressy, were all sunk by a single U-Boat, U-9, commanded by Kapitanleutnant Otto Weddigen. These three cruisers were all from the turn of the century and were being called the "live-bait squadron" even before they were torpedoed. In retrospect, the cruisers were not zigzagging in violation of orders to do so and further slowed and stopped to help their squadron-mates after the first torpedoing of the Aboukir, which they believed that had 'only' hit a mine. For his accomplishment, Weddigen was awarded Iron Cross and would have a Kriegsmarine U-Boat flotilla named after him in WWII. He would later die on Mar 18 1915 while trying to torpedo the HMS Neptune - he would not notice the HMS Dreadnought running over his boat, ramming and sinking it while setting up a torpedo attack.

The economic aspect of submarines sinking merchant ships was not considered for quite a while, primarily due to 'prize rules' - if one were attack merchant shipping, the expectation was that one would declare his presence to the merchant ship, order its surrender, take off its crew, put them in lifeboats, send them off towards the nearest point of land and only then sink the abandoned merchant. These rules are fairly easy to abide by when you're a large sailing ship, or a modern cruiser or battleship, but for a submarine, it just was not feasible. The sub would have to leave itself exposed for several hours while it went through all the steps for humane treatment of the crew, and the relative size of a sub compared to a merchant might even make such efforts impossible: Why surrender to a 600 ton hunk of metal when your cargo liner is several times larger?

The first round of Unrestricted Submarine Warfare began on Feb 1915, when the Kaiserliche Marine issued orders to its U-boats to attack merchant shipping without warning. The Germany Navy was actually not all that well-prepared for this, as many of its boats were not up-to-date models and so patrols set up to intercept ships coming in to England was very porous. Nevertheless, the subs did sink so many more ships when they did not have to abide to prize rules and were free to shoot torpedoes without prior warning, a luxury that previously was only afforded against warships or known troop transports.

It all came to a stop just 4 months later, May 1915, when U-20 sank the RMS Lusitania. The sinking cost the lives of 128 American citizens, and the possibility of drawing the US into the war was enough to get the German Navy to back down and cancel the campaign. It bears mentioning at this point that the prosecution of Unrestricted Submarine Warfare was a debate that raged on through the German high command since shortly after the beginning of the war. Proponents of the idea argued that it was the only way to strike back at Britain for their naval blockade of Germany, while its detractors cited the navy's unpreparedness to conduct a full campaign and the fear of drawing the ire of the US. For the moment, the anti-sub faction won, with one of the big factors being General von Falkenhayn promising victory in the Western Front through his upcoming Verdun campaign, obviating the need for a diplomatically risky submarine policy.

As it turned out, Verdun became a grinding battle of attrition that did not result in a decisive victory and von Falkenhayn was replaced by Paul von Hindenburg and Erich Ludendorff in Aug 1916. Since the cancellation of Unrestricted Submarine Warfare, U-boats had been relegated to their early-war role of naval support for fleet combat actions - the aforementioned net of U-boats at Jutland designed to sink RN battleships on their way to a decisive battle being the most notable example of this period. This limited policy did not work at Jutland nor at other junctions, but in the meantime the submarine arm of the Kaiserliche Marine had been expanding rapidly - more U-boats, better models. And now, with von Falkenhayn out, the stage was set for the German high command to allow for the reintroduction of Unrestricted Submarine Warfare - von Hindenburg and Ludendorff were willing to use any means at their disposal to win the war, and proponents of the campaign from the navy had drawn up statistics saying that if the U-boats could sink 600,000 tons of merchant shipping per month, Britain would collapse within 6 months.

Those standing against a renewed anti-shipping campaign knew that torpedoing merchants so aggressively would definitely draw the US into the war this time, but their objections were overruled by promises that the war would be over by then, that the US would not react in time, that the US would not be able to muster an army large enough to matter, and that even if they did join the war and muster an army the U-boats would prevent them from shipping troops across the Atlantic anyway.

Unrestricted Submarine Warfare finally resumed on Feb 1917 after months of preparations and deliberations following von Falkenhayn's dismissal. In Feb 1917, the U-boats sank 400k tons of shipping. In March 1917, 500k tons; in April 1917, 600k tons. By this time however the US had already joined the war, bolstered the Royal Navy by putting American destroyer escorts at the RN's disposal, and the RN itself started implementing the convoy system.

At this point I would like to address the question of why it took the RN so long to implement the convoy system. The main reasons come down to:

1. A belief that making groups of ships sail together would simply allow a U-boat to sink more in a single sitting - this was flat-out false - the RN had been effectively running "convoys" of dreadnought battleships escorted by destroyers for years now without major losses to submarines, and even merchant shipping convoys were in effect in the form of a coal cargo route between England and Norway, and ships running that particular route did not suffer heavy losses from submarines
2. A lack of escorts - the warship arm of the RN guarded its battleships jealously and allotted the majority of its destroyers to guarding them. Therefore, it lacked enough destroyers to serve as escorts for merchant ships themselves. This was a fairly valid reason and was offset by the addition of American escorts and an eventual slackening of allocation for the warship fleet once it became clear that the U-boats were a terrible threat to Britain
3. A lack of merchant discipline and technology - prior to official implementation of the convoy system, the Royal Navy invited groups of merchant captains to a conference to ask them about the feasibility of running in a convoy. The overall feeling was that it would either be very difficult if not outright impossible. Ships those days were still coal-fired, which made it difficult to produce consistent amounts of power from the engines, not withstanding that most merchant ships lacked engine telegraphs (read: throttles) which provided enough fine control to allow them to maintain formation. This was eventually remedied by closer coordination with RN officers and having the ships run with destroyer escorts. In the event, simply forcing the captains to man up and do it also worked.

As far as methods to attack or destroy U-boats, several approaches were taken: The most basic was simply turning the ship towards the U-boat and trying to ram it, although this would imply having already detected the U-boat in the first place. Depth charges and basic hydrophones (but not active sonar/ASDIC) was also invented and implemented in the latter half of the war, as was aerial patrols (not great considering limits on aeroplane technology) and the famous Q-Ships: merchant ships requipped with guns that would wait until they were attacked only to fight back as a wolf in sheep's clothing. Ultimately though, none of these measures were especially successful in destroying large numbers of U-boats, and the turning of the tide was more in the form of simply reducing losses dramatically via convoys rather than any sort of effective counter-measure.

After the implementation of convoying to Atlantic merchants, shipping losses dropped dramatically - and just in time too: The US Navy's liaison to the RN learned that in April 1917, Britain was down to about 3 weeks' worth of foodstuffs and other critical supplies. The Germans came close, but just not close enough - tonnage losses never hit the marks set by the German high command after April 1917, and by Jan 1918 losses were down to just 170k tons. The U-boat fleet never managed to strangle Britain as they had promised, the High Seas Fleet was inadvertently scuttled in Scapa Flow while the post-armistice peace negotiations were still on-going, the Treaty of Versailles imposed strict limits on the size of the new Kriegsmarine, and the stage was set for a new submarine campaign just 21 years later.

EDIT: I acknowledge that the original question was with regards to WWII submarines, but I felt that it needed to be put in the correct context by going back to the first Unrestricted Submarine Warfare campaign. I can talk about WWII U-boats in a separate post.

Because we were too cheap to properly test the design we went into the war with.


No I'm not joking, that's literally it. The torpedoes were expensive so they never tested them and just assumed it was all the captain's fault when they didn't work. Enough finally complained of hearing duds bounce off hulls that they finally tested them and found the fuse didn't work.

I just typed that up in an hour or so, but the basic outline had been clunking around in my head for months.

As for technical specs, this is going to come from googling, but:

U-9, the sub that sank 3 aging RN cruisers on Sep 22 1914:
Class - Type U-9
Launched - Feb 22 1910
Displacement - 493 tons
Length - 57m
Speed - 14.2 knots surfaced, 8.1 knots submerged
Best range - 3 250 nautical miles at 9 knots
Test depth - 50m
Complement - 4 officers, 25 men
Weapons - 4x 45cm torpedo tubes (2 bow, 2 stern) with 6 torpedoes carried, and a 50mm deck gun

U-35, the most successful U-boat of WWI, with 538k tons sunk:
Class - Type U-31
Launched - Apr 18 1914
Displacement - 685 tons
Length - 64.7m
Speed - 16.4 knots surfaced, 9.7 knots submerged
Best range - 8 790 nautical miles at 8 knots (note the dramatic increase, late war KM U-boats could reach the Eastern Seaboard of the US)
Test depth - 50m
Complement - 4 officers, 31 men
Weapons - 4x 50cm torpedo tubes (2 bow, 2 stern) with 6 torpedoes carried, and a 88mm deck gun

Type VIIC, the standard U-boat of the Kriegsmarine during WWII
Displacement - 769 tons
Length - 67.1m
Speed - 17.7 knots surfaced, 7.6 knots submerged
Best range - 8 500 nautical miles at 10 knots
Test depth - 230m
Complement - 44-52 men total
Weapons - 5x 53.3cm torpedo tubes (4 bow, 1 stern) with 14 torpedoes carried, and a 88mm deck gun

As a final point of comparison, the Gato-class submarine, which formed the majority of the USN submarine fleet during WWII (in the Pacific)
Displacement - 1 525 tons
Length - 95m
Speed - 21 knots surfaced, 9 knots submerged
Best range - 11 000 nautical miles at 10 knots
Test depth - 90m
Complement - 6 officers, 54 men
Weapons - 10x 53.3cm torpedo tubes (6 bow, 4 stern) with 24 torpedoes carried, and a 76mm deck gun

Most of this came from Castles of Steel. Despite the name, Robert Massie spends a lot of time discussing the U-boat war as well, especially since after Jutland there wasn't all that much to discuss with regards to surface actions anyway.

I've written many words about American torpedoes. Reposting them there so they don't get lost to archives:

quote:

One of the primary problems* with US torpedoes was that test shots were usually filled with cement or other inert material, which meant that war shots with explosives in them were much heavier.

This lead to a LOT of misses because the torps were running deeper than they were set to go at, but whenever BuOrd would try out their test torps, they'd come back saying everything's fine.

What I'm saying is that using lead weights wouldn't really solve the problems, as our fish would just continue to keep missing under the keels of ships.

* The other problem was with the magnetic detonator: Since water cannot be compressed, one of the advances in torpedo technology was to create a torpedo that would explode UNDERNEATH a ship, and the shockwave caused by the expanding wave of water would break the ship in half.

How do you tell a torpedo to detonate underneath a ship, without touching the ship? Magnets! The idea was that once the torpedo is directly underneath a huge metallic object, it would detect the large change in magnetism and detonate.

The problem? BuOrd would do all their test shots in the US, whose latitude is much higher than the equatorial / south-equatorial battleground of the PTO. This meant that the magnetic triggers would always be set wrong - the magnetic field changes as you move relative to the north and south poles.

Torpedoes shot in the tropics would either not notice a large enough change in the magnetic field to detonate, or they would detonate long before they ever reached the target.

** Finally, the third problem was with the contact detonator: BuOrd didn't anticipate the amount of force that would be imparted to the torpedo's head upon striking a target head-on - they were so strong that the contact pins on the detonator would either bend, break or simply fail to trigger.

So, even if you knew that your torps were running deep and set the running depth higher (by about 10 feet), and even if you knew that you shouldn't use the magnetic detonator and set the torps to contact detonation, you might still get a dud if you hit the target at a 90 degree angle to the hull


EDIT for more magnetic detonator comedy: The Germans had a similar experience with their own magnetic detonators, but for a far more specific reason. During the Invasion of Norway, U-boats patrolling near the Norwegian Fjords experienced large amounts of premature detonations because of the iron deposits underneath the ocean bottom

quote:

The gyroscope thing is actually a two-stage series of mishaps:

The first is a circular-running torpedo. As you described, torpedoes would have gyroscopes fitted to them so that subs could make off-angle torpedo shots. You'd program a certain heading for the torpedo to take, and the torp would turn to the new angle a few seconds after being shot out the tube.

The problem was that sometimes the gyroscope would not work correctly and so would never tell the torpedo to stop turning, hence being called a circular running torpedo since it would go around in circles. Since submarines tend to move rather slowly (at least relative to the torpedo) when submerged and making attacks, this can be deadly.

Here's where my content begins: In order to solve the problem of circular running, designers attached a SECOND gyroscope to torpedoes. If the second gyro measured a heading that exceeded the programmed turn by 15 degrees or more, the torpedo would self-destruct.

That would solve the problem completely, right? It would, except for the fact that sometimes, torpedoes would fail to shoot from their tubes correctly. Whenever this happened, the sub captain would just order the torpedomen to not touch the tube at all until the end of the patrol.

However, another US submarine was lost after the introduction of the second self-destruct gyro because one of their torpedoes failed to eject from the tube properly during a spread shot, and the submarine then began a turn for evasive action. Since the torpedo was still in the sub, and the sub turned 15 degrees beyond its original heading, the second gyro thought it was in a circular run and triggered the self-destruct, while it was still inside the torpedo tube.

And then of course the problems with magnetic detonators would have to take up a few chapters themselves:

In the beginning, most torpedoes used contact detonators. They'd have a 'pin' at the very front tip of the torpedo that would depress when the torpedo hits a solid object (preferably at a right angle), and the torpedo would explode. In fact, this is how most movies depict torpedo hits.

The problem with this approach is that it's wasteful. So much of your energy is being wasted as it channels 'up' out of the water, as in the big splash of water during when you see those movie-torpedoes.

The solution was to exploit the unique property of water. It's incompressible. If you exert force on a sponge, it shrinks. If you exert force on water, it just moves out of the way. If it can't move out of the way, something else has to.

Therefore, if you detonate a torpedo BELOW a ship, then the water, being incompressible, will instead 'push' the ship. Since your explosion is small relative to the ship, only a small part of the ship will be pushed up. As it gets pushed up, the weight of the opposite ends of the ship will bear down on the small portion affected by the torpedoes explosion. In effect, the ship breaks its own back.

Only, how do get a torpedo to detonate BELOW a ship? Answer: Magnets! Rig a magnet to the head of a torpedo, and when it passes under the great metal mass of a ship, the magnet should detect a great change in the magnetic field. Attune the detonator to the magnet, and you'll theoretically have something that blows up when it passes under a ship.

The problem was that both the German and American Navies did their testing without taking into account the effect of the magnetic field exerted by the EARTH. The Americans tested theirs in Narangasett Bay in Rhode Island, which meant that when they were fighting in the equatorial areas of the Pacific Theater, the magnetic influence was only half as powerful as it was relative to the tests. As a result, most of the torpedoes either detonated early, or never detected a sufficient change and just sailed right under the ships.

The Germans had a slightly different problem - when they deployed their U-Boats to interdict British ships during their invasion of Norway, they found that their torpedoes kept detonating early, even though it seemed to work just fine everywhere else. The issue? Iron deposits. In the shallow waters of the Norwegian Sea, clumps of iron below the sea floor exerted a powerful enough change in the magnetic field that it caused the torpedoes to detonate as it sailed above them. It got so bad that even the best U-Boat aces just up and refused to take shots during the 1940 campaign until the kinks in the system were worked out.

quote:

I cannot believe there's no youtube video of the Konovalov being struck by her own torpedo. "You arrogant rear end in a top hat! You've killed us!"

A similar situation actually happened with the German's first-generation acoustic-homing torpedoes. They were supposed to travel straight for about 400 meters, then turn towards the noisiest target it could hear.

The problem was that if you're shooting at bunch of transports plodding along at 7 to 10 knots nearly a klick away, and your own sub is making waves taking evasive action, the torpedo is going to recognize YOU as the noisier target. The results are rather obvious.

The Germans then determined that it was only prudent to use these particular torpedoes against the faster running convoy escorts such as Destroyers or Corvettes, and even then only when they're moving faster than 15 knots.

http://en.wikipedia.org/wiki/HMS_Gotland_(Gtd)#cite_note-9

As a final note, there's also the story of the HMS Gotland, a Swedish diesel-electric submarine that managed to get close enough to the USS Ronald Reagan to snap some pictures of it through its periscope, effectively signifying that the carrier could have been sunk if it was a live-fire exercise.

Because the same single government agency, the Newport Torpedo Station, was by act of Congress the entity in charge of designing them, building them, and testing them. And the latter pretty much never happened.

It wasn't just the fuse. There were a bunch of problems and each problem was masked by others. The first problem was that they ran too deep. Tests that were done involved a dummy concrete warhead, which was lighter than the actual live warhead. And eventual development replaced the original-design warhead with an even heavier one. So they'd under-run the target and the magnetic detonator just wouldn't sense it and blow the thing up. The Bureau of Ordnance eventually realized this and in the meantime the sub captains started setting them up to run at zero depth, which makes them easier to spot and avoid but at least they'd get close enough for the magnetic detonators to react. So once that change was made, they started getting more hits, which revealed the second problem: now the magnetic detonator was revealed to suck and torpedoes would start going off too early. BuOrd refused to believe this expensive fancy-rear end magnetic detonator could possibly be flawed, and one of the inspectors actually tampered with a test article in order to shift blame away from the design and towards the crews, so submarine captains started deactivating the magnetic detonators. Once that was done, it was discovered that the contact fuse also sucked, it was so massive and had so much inertia that when a torpedo ran straight into the side of the target, the kind of hit crews were trained to aim for, the elements in the fuse would bend and jam and not actually set the torpedo off. Eventually those fuse components were redesigned to be lighter. By the end of the war it was a reasonably reliable weapon but if it had been that way in the first place, *man*. One sub would have crippled or sunk three Japanese carriers in 1943, but the 7 "hits" he achieved were all ones set off too early by the faulty magnetic detonators.

I find that summary of German submarine warfare to be automatically bullshit, because you barely mention the role of Q-ships. These were disguised merchant ships that would blow the gently caress out of German submarines that had surfaced and allowed vessels time to discharge their crew into lifeboats in accordance with the laws of war. They are a great example of how the British refused to play good cricket in the North Atlantic when the drat Germans were doing their best to follow the laws of war. Not mentioning them in a history of sub warfare during WWI is like not mentioning the Laconia Incident in a history of sub warfare during WWII. It's an automatic indication that you are approaching the subject from one single point of view, a completely bullshit one.

Did the Q-ships actually sink or damage enough subs to make an impact on the German anti-shipping campaign? I can only find a handful of merchants that were converted and it doesn't seem like just a few ships converted to killers that are only effective when not using the convoy system and are only really effective vs submarines that declare themselves before launching torpedoes would have much effect. Even if they're loaded with cork or whatever to make them resistant to the first torpedo, I have a hard time imagining a destroyer in WW2 conducting an effective surface action vs a sub after taking a torpedo, let alone a converted merchant in WW1 pulling it off.

e: Looking at WW1 Q-Boats they managed to sink 14 submarines for 27 Q-Boats (according to wikipedia) which is a pretty horrific loss rate for a weapon that's designed to deal with submarines and only submarines.

That's totally my mistake and appreciated feedback for you to point it out. I omitted it in the running outline I was keeping in my head and so just threw it in there at the last minute without really giving it its proper due.

The Q-Ships didn't sink a lot of U-boats (and I daresay nothing was especially effective at sinking U-boats in WWI), but they did represent a significant morale-boosting effort in a war where morale and public perception was as important as anything else, and some Q-Ship engagements were deemed important and heroic enough to merit Victoria Crosses and other such recognition (and in fact my primary source does spend some chapters talking about Q-ships specifically). Another related tactic was the practice of having an RN submarine in tow, to torpedo the U-boat after it had surfaced and stopped the "merchant"

I of course have no claim at all to be authoritative, and I acknowledge that my write-up does and will have flaws.

The Royal Hospital Chelsea is next to it as well which is a nice place to have a walk around. Else, in Whitehall theres the Household Cavalry Museum at Horse Guards, the Guards Museum at Wellington Barracks and the Churchill War Bunker behind Downing Street (ish). I wouldn't recommend the latter however as when it boils down to it they're just underground offices and its fairly pricey to get in.

If you can get out of London, I strongly suggest the Tank Museum at Bovington, the Fleet Air Arm Museum at Yeovil and really the big one, the Historic Dockyard at Portsmouth and HMS Victory - all are excellent and very big.

In related news I absolutely cannot imagine how awful and frustrating and horrifying it would have been to repeatedly fire dud torpedoes. You're in a steel tube with a couple dozen other dudes with no showers and bad food for weeks at a time, you do well enough to crawl your tube into an attack position against something, you do all the calculations right to deliver your ordnance, you think you're about to strike a blow for Uncle Sam, and then THUNK. You didn't sink anything, any escorts in the area are now hunting for you, and you just lost confidence in the primary weapon that your military profession is designed to employ. Gross.
