I remember several years ago reading about the Japanese army crossing through a swamp in WWII and the crocs ate hundreds of them.
"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 1,000 Japanese soldiers that entered the swamps of Ramree, only about 20 were found alive.
Good crocs
