Citation... On 16 June 1943, Maj. Zeamer (then Capt.) volunteered as pilot of a bomber on an important photographic mapping mission covering the formidably defended area in the vicinity of Buka, Solomon Islands. While photographing the Buka airdrome. his crew observed about 20 enemy fighters on the field, many of them taking off. Despite the certainty of a dangerous attack by this strong force, Maj. Zeamer proceeded with his mapping run, even after the enemy attack began. In the ensuing engagement, Maj. Zeamer sustained gunshot wounds in both arms and legs, 1 leg being broken.

Despite his injuries, he maneuvered the damaged plane so skillfully that his gunners were able to fight off the enemy during a running fight which lasted 40 minutes. The crew destroyed at least 5 hostile planes, of which Maj. Zeamer himself shot down 1. Although weak from loss of blood, he refused medical aid until the enemy had broken combat. He then turned over the controls, but continued to exercise command despite lapses into unconsciousness, and directed the flight to a base 580 miles away. In this voluntary action, Maj. Zeamer, with superb skill, resolution, and courage, accomplished a mission of great value.
