Today in military history: Admiral Yamamoto, Pearl Harbor mastermind, is shot down

On April 18, 1943, Admiral Isoroku Yamamoto, mastermind of the attack on Pearl Harbor, was shot down by American pilots.

American forces have begun to turn the tables in the Pacific. Midway had seen the decimation of the Japanese carrier fleet, and the Japanese Navy had failed to cut off American Marines at Guadalcanal. Admiral Yamamoto planned an inspection tour of various bases in the Solomon Islands, and his itinerary was radioed to the bases he would visit.

But it turns out American codebreakers were also listening. The Japanese Admiral’s travel plans made it into the hands of Admiral Chester W. Nimitz, and before long the 347th Fighter Group was on their way to rain on Yamamoto’s parade. 

A squadron of P-38s led by Captain Thomas G. Lanphier and Major John W. Mitchell took off from Guadalcanal. They soon intercepted the Japanese formation of two Mitsubishi G4M “Betty” bombers and six Mitsubishi A6M “Zero” fighters.

Yamamoto’s Betty was shot down by Captain Lanphier, who also claimed to have shot down a Zero. Lieutenant Rex Barber shot down the second Betty carrying many of Yamamoto’s senior staff officers. Barber and Lieutenant Besby Holmes also each claimed to have shot down Zeroes as well. The last pilot from the “killer flight,” Lieutenant Raymond Hine, never returned to base.

The mission, code-named Operation Vengeance, had been a success. Pearl Harbor had been avenged.
