What happened to admiral yamamoto?

Answer 1

Yamamoto died when his plane was shot down over Bougainville, in the Solomon Islands, in April 1943.

The US had developed the ability to decrypt much Japanese coded radio traffic, and knew from this that Yamamoto would be on an inspection trip in the Solomons. The US wanted to take out Yamamoto, but did not want to tip the Japanese that the US was reading their radio messages. The only fighter planes the US had with the range to reach the area where Yamamoto was going to be were P-38 Lightenings, the strangest looking fighter planes of the war, with twin engines and twin tails. So occasional P-38 patrols were begun in the area where the Admiral was expected.

On the day Yamamoto was due a large patrol was sent out. Yamamoto and his staff were traveling on two "Betty" bombers, and both were shot down. US Army Air Force Captain Thomas Lamphier, of Detroit, was credited with destroying Yamamoto's plane. The wreckage of the crashed Betty bomber in which Yamamoto died still rests in the jungle on Bougainville.
