I remember a story from WW11 where Americans had pushed thousands of japs to the bank of a river. The crocs came out at night after the japs and killed hundreds if not thousands, don't rtemember. I do remember Gis saying they could hear the japs shooting and screaming in fear and agony all night, said they felt sorry for them. A croc will stick their meal under roots in the river bank, kinda like storing their food to eat later. What was left come daylight were very happy to surrender. POWDERMAN.
