Sub-Lieutenant Saburō Sakai (坂井 三郎, Sakai Saburō, 25 August 1916 – 22 September 2000) was a Japanese naval aviator and flying ace ("Gekitsui-O", 撃墜王) of the Imperial Japanese Navy during World War II. Sakai had 28-64 aerial victories (including shared) by official Japanese records, while his autobiography Samurai!, co-written by Martin Caidin and Fred Saito, claims 64 aerial victories. Such discrepancies are common, and pilots' official scores are often lower than those claimed by the pilots themselves, due to difficulties in providing appropriate witnesses or verifying wreckage, and variations in military reports due to loss or destruction.
On 3 August 1942, Sakai's air group was relocated from Lae to the airfield at Rabaul.
On 7 August, word arrived that U.S. Marines had landed that morning on Guadalcanal. The initial Allied landings captured an airfield, later named Henderson Field by the Allies, that had been under construction by the Japanese. The airfield soon became the focus of months of fighting during the Guadalcanal Campaign, as it enabled U.S. air power to hinder the Japanese attempts at resupplying their troops. The Japanese made several attempts to retake Henderson Field, resulting in continuous, almost daily air battles for the Tainan Kōkūtai.
U.S. Marines flying Grumman F4F Wildcats from Henderson Field on Guadalcanal were using a new aerial combat tactic, the "Thach Weave", developed in 1941 by the U.S. Navy aviators John Thach and Edward "Butch" O'Hare. The Japanese Zero pilots flying out of Rabaul were initially confounded by the tactic. Saburō Sakai described their reaction to the Thach Weave when they encountered Guadalcanal Wildcats using it:
"For the first time Lt. Commander Tadashi Nakajima encountered what was to become a famous double-team maneuver on the part of the enemy. Two Wildcats jumped on the commander's plane. He had no trouble in getting on the tail of an enemy fighter, but never had a chance to fire before the Grumman's team-mate roared at him from the side. Nakajima was raging when he got back to Rabaul; he had been forced to dive and run for safety."
On 7 August, Sakai and three pilots shot down an F4F Wildcat flown by James "Pug" Southerland, who by the end of the war became an ace with five victories. Sakai, who did not know Southerland's guns had jammed, recalled the duel in his autobiography:
"In desperation, I snapped out a burst. At once the Grumman snapped away in a roll to the right, clawed around in a tight turn, and ended up in a climb straight at my own plane. Never before had I seen an enemy plane move so quickly or gracefully before, and every second his guns were moving closer to the belly of my fighter. I snap-rolled in an effort to throw him off. He would not be shaken. He was using my favorite tactics, coming up from under."
They were soon engaged in a skillfully maneuvered dogfight. After an extended battle in which both pilots gained and lost the upper hand, Sakai shot down Southerland's Wildcat, striking it below the left wing root with his 20 mm cannon. Southerland parachuted to safety.
Sakai was amazed at the Wildcat's ruggedness:
"I had full confidence in my ability to destroy the Grumman and decided to finish off the enemy fighter with only my 7.7 mm machine guns. I turned the 20 mm cannon switch to the 'off' position and closed in. For some strange reason, even after I had poured about five or six hundred rounds of ammunition directly into the Grumman, the airplane did not fall, but kept on flying.
I thought this very odd — it had never happened before — and closed the distance between the two airplanes until I could almost reach out and touch the Grumman. To my surprise, the Grumman's rudder and tail were torn to shreds, looking like an old torn piece of rag. With his plane in such condition, no wonder the pilot was unable to continue fighting! A Zero which had taken that many bullets would have been a ball of fire by now."
Not long after he downed Southerland, Sakai was attacked by a lone Douglas SBD Dauntless dive bomber flown by Lt. Dudley Adams of Scouting Squadron 71 (VS-71) from USS Wasp. Adams scored a near miss, sending a bullet through Sakai's canopy, but Sakai quickly gained the upper hand and succeeded in downing Adams. Adams bailed out and survived, but his gunner, R3/c Harry Elliot, was killed in the encounter. According to Saburō Sakai this was his 60th victory.
