Career
Jaccard enlisted in the United States. Naval Reserve October 29, 1940. He later underwent flight training and upon graduation was commissioned Ensign September 27, 1941. Reporting to famed carrier United States Ship Enterprise in April 1942, Ens.
Jaccard took part, June 4, 1942, in one of the most important battles in all naval history, the Battle of Midway.
As American carrier groups moved to meet the Japanese thrust at Midway Island, Jaccard, as part of Scouting Squadron 6, attacked enemy carriers during the morning, knocking out Akagi and Kaga. That afternoon the squadron carried out another devastating attack, sinking carrier Hiryu, Ens.
Jaccard also participated in attacks in the Japanese cruisers Mikuma and Mogami. There was confusion in the initial dive as McClusky called out a dive on one carrier, but then dove on the other (Kaga and Akagi).
This caused VS-6 and VB-6 planes to co-mingle on the first carrier, leaving Lieutenant
Richard Best to call off the final two sections of VB6 to attack the second carrier. Ensigns Pittman and Jaccard were flying as wingmen to McClusky. Pittman should have been the second man down after McClusky, but because of confusion over the ship they were diving on, it was Ens.
Jaccard who followed McClusky down.
During his dive he apparently mistook his undercarriage lever for the wing-brake lever and slowed his plane by lowering his wheels instead of his brake flaps. While he apparently missed his target on that dive, he is credited with a hit on the Hiryu (later the same day) and on a Mogami class cruiser the next day.
Ens. Jaccard flew with Bombing Squadron 6 in support of the landings at Guadalcanal and Tulagi as well as the Battle of the Eastern Solomons in which Enterprise was severely damaged.
Bombing 6 was ordered to Efate where a four plane division including Ens. Jaccard was detached and sent to the United States Ship Wasp.
Ens. Jaccard was killed when Wasp was torpedoed and sunk September 15, 1942.
