Tuhia tētahi tohutoro mō tēnei wāhanga - I whawhai a McGaha i te pakanga o Guadalcanal me te raki o Solomons
i mua i tana whai wāhi ki te pakanga ki te whakahoki mai i ngā Piripiana mai i te mana o Hapani. I te Hui-tanguru 7, 1945, i mahi ia hei rangatira rangatira i te Pakanga o Luzon. I taua ra, tata ki Lupao, Luzon, i maha nga wa i tukuna ai ia ki te ahi a te hoariri hei awhina i nga hoia whara, i arahi i tana roopu i muri i te whara o te kaiarahi o te roopu, me te hiahia ki te pupuhi i te ahi Hapanihi ki a ia kia taea ai e etahi atu te mawhiti ki te ahuru. Mo enei mahi, i tohua ia mo te Medal of Honor ka whakawhiwhia ki a ia he komihana pakanga ki te tuarua. Katahi ka tukuna a McGaha mai i te ope taua, engari kaore i roa ka whakauruhia ano hei rangatira rangatira ka tu ki Fort Benning, Georgia. I whakaaetia tana tono mo te Medal of Honor kotahi tau i muri i te pakanga, i te Paenga-whāwhā 2, 1946. I te wa o te huihuinga i te White House i te Poutu-te-rangi 27, 1946, i whakawhiwhia e te Perehitini a Harry S. Truman a McGaha me tetahi atu tangata, a Navy Commander Richard O'Kane, ki nga Tohu Whakahonore.
