Will joined the Army from West Winfield, New York in December 1940 and by March 30, 1945 was serving as a first lieutenant in Company K, 18th Infantry Regiment, 1st Infantry Division. During a firefight on that day, near Eisern, Germany, he rescued three wounded men, single-handedly disabled two German machine gun nests and led his squad in the capture of two others, all despite his own injuries. Mortally wounded while leading a charge on the enemy, Will was posthumously awarded the Medal of Honor seven months later, on October 17, 1945. He is buried at the Netherlands American Cemetery in Margraten, South Limburg, the Netherlands.
