From the 320th Engineer Battalion 1942-1945 Regimental History Book
During the morning of November 12, efforts to continue the construction of the infantry support raft ferry under cover of smoke were made by men of Company C but had to be abandoned due to heavy enemy mortar and artillery fire on the site, which wounded two men before the work was called to a halt. Men of Company A, withdrawing from their outpost security position, were caught in the mortar and artillery barrage, and before they could reach cover, PFCs Donald B. Roos and Donald R. Gaspard were killed, and three men were wounded.
