Lieutenant Colonel Chandler W. Johnson, commander of the 2nd Battalion, 28th Marine Regiment, 5th Marine Division, ordered Marine Captain Dave Severance, commander of Easy Company, 2nd Battalion, 28th Marines, to send a platoon to seize and occupy the crest of Mount Suribachi. First Lieutenant Harold G. Schrier, executive officer of Easy Company, who had replaced the wounded Third Platoon commander, John Keith Wells, volunteered to lead a 40-man combat patrol up the mountain. Lieutenant Colonel Johnson (or 1st Lieutenant George G. Wells, the battalion adjutant, whose job it was to carry the flag) had taken the 54-by-28-inch/140-by-71-centimeter flag from the battalion's transport ship, , and handed the flag to Schrier. Johnson said to Schrier, "If you get to the top, put it up." Schrier assembled the patrol at 8 a.m. to begin the climb up the mountain.
