It took us a while to gain air superiority. Their fighters gave us fits in the beginning IIRC. We did have the advantage of numbers though. I'm not positive but I think it was closer to the end of the war when we were able to strike their production facilities with great success.
One America pilot said he owed his life to a German pilot.
The American was flying a P-40 in North Africa and got in trouble with a new model Me-109, the standard operating procedure was to do a nose dive to get the other plane off your tail.
As he was headed straight down at full throttle, the German flew alongside and gave him a salute, he said that probably saved his life as he never tried than again.
We got back 98% of our POWs from Germany, (the Russians kept a lot of those missing) but we only got back about 40% of our prisoners from Japan.
I had an uncle who served in the Marines in the south Pacific and was in on most of the landings and was involved in a lot of jungle warfare and he said as cruel as the Japanese were, and they were extremely cruel, he said he hated the muslim islanders much more.
Many of them had been taught that to take the head of a Christian would guarantee them admittance to paradise and they did just that when they could get the chance.
On the POWs, I knew a nice lady whose husband was in charge of the German POW camp at Tullahoma, one particular German Captain gave them several oil paintings he did while there, she still had them framed and in her home, they were nicely done.
My great uncle commented on how tiny the average Japanese soldier was. They were often about half a foot shorter and forty pounds lighter than the Americans, or so he recalled. Of course, this was perhaps towards the end of the war when they were sending out younger soldiers and rationing was tighter.
The Japs would shoot up on morphine just before a banzai bayonet charge, if their legs were shot off, they would keep charging on the bloody stumps and so when you were dug in and expecting a counter attack, the thing to do was cut off the end of bullets and cut an X in the ends of them.
A full metal jacket would go right trough a man but a dum dum would cut him in half. A violation of Geneva Conventions, but who was checking.
Well, that's about all I want to talk about the realities of warfare, I just wish so many wouldn't take the sacrifices of generations before them so lightly.
They say if you don't want anyone to get your goat, don't tell them where it's tethered but nothing gets to me quicker than some young punk blaming America for all the ills of the world!!!
