When Crocodiles are more dangerous than bullets

At the Battle of Ramree Island (off the coast of Burma) in WW2, a Japanese retreat turned disastrous as they fled through a crocodile-infested swamp.

"That night [of the 19 February 1945] was the most horrible that any member of the M.L. [motor launch] crews ever experienced. The scattered rifle shots in the pitch black swamp punctured by the screams of wounded men crushed in the jaws of huge reptiles, and the blurred worrying sound of spinning crocodiles made a cacophony of hell that has rarely been duplicated on earth. At dawn the vultures arrived to clean up what the crocodiles had left. . . . Of about one thousand Japanese soldiers that entered the swamps of Ramree, only about twenty were found alive."
