Picture of the day

The Kriegsmarin was just settling on a proper modern stabilized midget submarine at war's end. It sort of resembled the DPRK Yugo class submarine. It was designed to slip throgh a neglected Allied defence window. Luckily for the Allies they had few at war's end and very limited berthing options at the end of the war. Not enough of these made it out of the shipyards. Zeehund iirc.

The Seehund was a fine midget sub for the era, but as is typical with midgets, they lost far more hulls than the ships they managed to sink. Their limited capability would not have served to shift the tide of war, either by virtue of their late appearance (it was nearly 1945) or the fact that they could not hope to intercept the mid Atlantic convoys.

I think they were actually intended as coastal last ditch boats, saw one in a museum in Cuxhaven, but never uploaded the pics. Seems surprisingly small compared to Japanese midgets.

That late in the war, they were not much but last ditch. And yes, quite small, only half the length of the Japanese Type A, for example, and carrying their two torpedoes externally.
 
The Brits sure liked the Polish contribution to the war effort but after WWII seemed to have considered themall to be an embarassing burden. Correct me if I am wrong. . .

Just read a book on this issue. Yes the Brits wanted the contribution of the Poles and it is possible they would have lost the Battle of Britain without them. The Poles provided the most successful squadrons of the B of B by a large margin. The Poles fought gallantly and in large numbers alongside the allies in WW2. The Poles were the one who finally took Monte Cassino. In spite of the fact they they new they were being sold out they continued to fight with great gallantry right until the end of the war. At the end of WW2 the Poles were totally betrayed by both the British and Americans. A large part of eastern Poland was taken by the USSR with the approval of both Britain and the USA. If anything Roosevelt was even worse than Churchill in this regard. The Poles were portrayed as an embarrassing burden so that the public would not be worried about the treachery behind the scenes. The Poles were simply trying to get the Brit and USA to honour their commitments to Poland's freedom. Overall a very sorry chapter in the the History of both Britain and the USA. Remember Poland had the highest loss rate of any country during WW2, approximately 30% of its total population so I think they had a right to be pretty steamed when they were betrayed.

The Poles should be praised for their contributions not thought of as pests. And no I am not Polish nor do I have any Polish heritage so no axe to grind here. Just demonstrates how well propaganda works.
 
Not a lot of information available for this one.

That pile of brass probably weighs 300 pounds; I wonder what the loaded, unfired ammo weighed.

Great Post! Could not agree more! (I'm not of Polish descent either)
 
I have Canadian friends from Poland, such great and loving ppl.The investigation into Soviet era crimes against humanity is a dead nuts serious activity in modern day Poland. Poles are demanding satisfaction on these crimes against the Żołnierze wyklęci (cursed soldiers).

an often used pic of Polish Home Army grenades. These were designed by professionals, not bubba, this included the mechanics/physics and the chemical/pyrotechnic elements of the munitions. The filipinka had a sophisticated contact fuze like the British #68 grenade or the Italian 'red devil' grenade. You will not find any info in print about the KCLO3 based explosive used in these munitions. I have done a fair bit of drilling for that - not much. Military secrets stay that way for a very long time 'because reasons.'

I have Canadian friends from Poland, such great and loving ppl. I met this chap's s.o. a while ago in the course we were both taking. I had bought a t shirt with the AK logo boldly emblazoned on it, mainly bcs. I could not find a t shirt with the Belgian Comet Line logo on it - which nobody would have the faintest idea about in the entire Atlantic provinces anyways. Even still, a typical Dartmouth denizen once asked me if my AK t shirt was a Dartmouth Whalers t shirt lol! I had that shirt until it was completely worn out. This Polish Cdn. classmate of mine knew full well what it meant, & we struck up a friendship. It started me on an informal yet fairly constant study of Polish & Eastern Euro history, often concentrating on the WWII period through the Soviet & Post Soviet era. To get background, I even occassionally delved into the late dark age history of Europe. Such a fascinating thing to read about! I learned there are many Soviet era Poles living in hiding in Sweden for example. The investigation into Soviet era crimes against humanity is a dead nuts serious activity in modern day Poland. Poles are demanding satisfaction on these crimes against the Żołnierze wyklęci (cursed soldiers).

Potassium chlorate is an oxidizer, mix it with about anything and it becomes explosive, sulfur works well. don't ask me how I know .:redface:

Absolutely. It has been used all the way along for nasty purposes ever since Claude Louis Berthollet's tragic experiments with it in the 18th century. The properties are well known. Still, AK secrets remain AK secrets, & you ain't getting them.

A dramatization of the notorious Lavoisier - Berthollet gunpowder incident:

C0300160-Berthollet_s_Gunpowder_Experiment.jpg


Following his research into chlorine, the French chemist Claude-Louis Berthollet (1748-1822), believed that the replacement of the saltpetre (potassium nitrate) in gunpowder by potassium chlorate would produce a more powerful explosive. In 1788, the chemist Antoine Lavoisier, a Director of the Régie des Poudres, organised a trial production run of Berthollet's formulation. In attendance at the trial were Berthollet, M. Chevraud, a commissioner in the gunpowder service, his sister Mlle. Chevraud, and M. & Mme Lavoisier. According to his published account, Lavoisier had given strict safety instructions, but the factory manager M. Le Tort did not completely follow them, resulting in an explosion in which Le Tort and Mlle. Chevraud were killed. Berthollet, M. Chevraud and the Lavoisiers were unharmed, being some distance away. The potassium chlorate trials were abandoned.
Things are fun until they are not fun.

In the ditch, and thrown a track - she's buggered.

Nope, break track, drag it back onto the road, put track back together on the Stug and get it back in the fight. The 12tonner is just a simple recovery unless it has a gun in tow then it could be kinda weird.
