Sorry if this doesn't make to much sense I'll try to explain it. Since I'm Canadian and while I was in high school I mostly learned about WWI. One big thing we learned was when the allies and Germans supposedly ended up having soccer matches and trading small gifts and singing Christmas songs during Christmas one year. Another thing is how the allies got "good" treatment when they got captured. Are there recorded instances of this kind of stuff happening in WWII? To me it seems like in WWI soldiers on both sides had more respect for each other then in the second world war.
There were many.
One that comes to mind is the Stigler incident, wherein the Luftwaffe fighter pilot Franz Stigler escorted a badly damaged American B-17 bomber out of Germany rather than shoot it down. Stigler even tried to signal to the B-17 crew to tell them to turn towards neutral Sweden, which would have been easier to reach than England, though the B-17 ended up just barely reaching England anyways.
Another incident that was quite remarkable were the actions of Commander Kudō Shunsaku after the Second Battle of the Java Sea. As captain of the destroyer Ikazuchi, Kudō was responsible for rescuing 442 survivors from the destroyers HMS Encounter and USS Pope, which had been sunk in the aforementioned battle, despite the fact that the rescue mission put Ikazuchi at risk of enemy submarines, hampered the effectiveness of the ship, and likely cost the ship a fair bit of oil - reading accounts of Japanese destroyers during even the periods of the war when Japan was on the offense shows that they were often had to conserve fuel very carefully. Ikazuchi was far from the only ship to rescue enemy survivors during the war - many U-Boats attempted to do the same, for example - but the story stands out amidst the plentiful stories of Japanese brutality in the Pacific Theatre of combat.
As /u/eightgear says yes there were many, especially if the enemy was injured or shipwrecked - there was always a spare cigarette for an injured solider or a tot of rum for the survivor of a sinking.
The story of escorting an enemy plane is fairly common for both sides. There are numerous stories from the Battle of Britain of the same thing or an enemy circling a downed pilot so that they could be rescued.
Its a strange trait of human nature that we can be trying to kill each other and then minutes later be sharing a few words, food, cigarettes or photos of loved ones etc.
There was the case of Douglas Bader an RAF fighter pilot. He had lost both legs before the war, but still joined the RAF. He was shot down over Germany, captured and put in a POW camp. One of his artificial legs was damaged beyond repair, and the Lufwaffe offered to allow safe passage for an RAF plane to drop a replacement leg for him. The RAF did drop a new leg but as part of a normal bombing raid. (Bader had already attempted to escape before the new leg arrived, and made another escape attempt after it had been delivered!)
