If you know an interesting bit of trivia that involved animal usage during World War II, feel free to post.
(1) The Russians trained dogs to run underneath enemy tanks. Remote control bombs were strapped to the dogs backs, and these were subsequently detonated.
(2) The U.S. partially froze bats and placed time-bombs inside their abdomens. The bats were to be dropped out of B-29s and would 'thaw out' on the descent. During testing, the bats did so well that they destroyed a church and damaged a hangar in New Mexico.
(3) In the first attempt to create a 'smart' bomb, pidgeons were to be placed inside guided bomb units. The pidgeons would peck at a screen when they saw the target they were trained for. A scientists trained a group of pidgeons for this, but I don't believe they were ever used in combat.
(4) This is a story told by my high school history teacher. During World War II, some GIs were trying to cross some fortified position in Northern Italy. The entire area was land-mined. However, the GIs kept seeing this German dog trot back and forth eating scraps off the ground. The GIs coaxed the dog over, fed it some c-rations, and then followed it back to the German rear area. Apparently the dog knew where the landmines were!
