Michels landed on the southern end of Iwo Jima with his unit on February 19. He was wounded by shrapnel to his thumb from an enemy mortar at the base of Mount Suribachi on February 21. On February 23, Michels was part of the 40-man combat patrol that was sent at 8 AM to climb up the east slope of Mount Suribach to seize and occupy the crest. First Lieutenant Harold Schrier, who led the patrol, was to raise an American flag he was given to signal that the mountaintop was captured. Once Schrier and his men were on top, a Japanese iron water pipe was found to attach the flag unto. Lieutenant Schrier, Corporal Charles Lindberg, and Sergeant Henry Hansen, tied the flag unto the pipe while Private Phil Ward held the bottom end of the pipe horizontally off the ground. Platoon Sergeant Ernest Thomas was in among the three Marines watching, armed with his rifle and a grenade in hand, while Michels with his carbine was watching for an enemy attack on the group while this was all going on. The flagstaff was then carried to the highest point on the crater and raised and planted in the ground by Schrier, Thomas, and Hansen at approximately 10:30 AM. Seeing the raising of the National colors immediately caused a cheering reaction from the Marines, sailors, and Coast Guardsmenon the beach below and from the men on the ships near the beach at the southern end of the island. After the flag was raised, Michels was photoed near the flagstaff by Marine Corps photographer Staff SergeantLouis Lowery. In the photo he is shown holding a M1 carbine in a defensive position. Shortly thereafter, fighting took place between the Marines and Japanese because of the flag raising, the Japanese were hiding in caves on the mountain when they saw the flag go up. Some two hours later, in order for the American flag to be seen more easily from the ships, beaches, and land on the north side of Mount Suribachi, it was decided that a larger flag should be sent up Mount Suribachi to replace the first flag. The replacement flag attached to another and heavier pipe was raised on the mountain top simultaneous with the lowering of the first flagstaff. It was the black-and-white photograph shot of the second flag-raising by Associated Press photographer Joe Rosenthal which became renowned, made the second-flag raisers famous, and led to the creation of the huge Marine Corps War Memorial in 1954, at Arlington, Virginia.
Michels was immortalized in Marine Staff Sergeant Lou Lowery's photograph of the first American flag flying over Mount Suribachi on Iwo Jima. Michels is shown on guard with his M1 carbine while three other members of the patrol place the flagstaff more securely into the ground to keep it vertical in the high winds on the volcano.
