Despite the large numbers of Japanese troops in the immediate vicinity, Schrier's patrol made it to the rim of the crater at about 10:15 a.m., having come under little or no enemy fire, as the Japanese were being bombarded at the time. The flag was attached by Schrier and two Marines to a Japanese iron water pipe found on top, and the flagstaff was raised and planted by Schrier, assisted by Platoon Sergeant Ernest Thomas and Sergeant Oliver Hansen (the platoon guide) at about 10:30 a.m. (On February 25, during a CBS press interview aboard the flagship about the flag-raising, Thomas stated that he, Schrier, and Hansen had actually raised the flag.) The raising of the national colors immediately caused a loud cheering reaction from the Marines, sailors, and coast guardsmen on the beach below and from the men on the ships near the beach. The loud noise made by the servicemen and blasts of the ship horns alerted the Japanese, who up to this point had stayed in their cave bunkers. Schrier and his men near the flagstaff then came under fire from Japanese troops, but the Marines quickly eliminated the threat. Schrier was later awarded the Navy Cross for volunteering to take the patrol up Mount Suribachi and raising the American flag, and a Silver Star Medal for a heroic action in March while in command of D Company, 2/28 Marines on Iwo Jima.
