There is certainly no shortage of literature and movies based on the Second World War. Even a history major at school would struggle to actually cover the breadth of covert operations that the Axis and Allies pulled off.

Some of these operations were successful, while others definitely weren't. Win or lose, these ops were all pretty crazy. Here are some of the lesser-known secret operations that could basically have a full movie based on them. Read on to learn more about these real-life events.

The infamous Unit 731, commanded by Major Shiro Ishii, was known to conduct horrible experiments on Chinese citizens. From hypothermia to induced heart attacks and infectious disease — nothing was off limits.

When the Japanese felt that defeat was looming, Ishii planned a massive biological attack on Southern California. Five long distant subs would launch dive bombers carrying plague-infected fleas. The plan was approved but logistics stopped it before the surrender.

So, the British would skip their bombs along the river surface to strike the dam. They bombed four of them and two hydroelectric plants were disabled because of the flooding. 1,600 civilians were killed.
