Troops began to go ashore at two beaches at 08:30 on 20 November. The initial landings on Red Beach went according to plan with the assault troops moving rapidly inland after an uneventful trip on the ocean side of the island. Their progress off the beach was slowed only by an occasional sniper and the need to negotiate their way around the debris and water-filled craters left by the air and naval bombardment. The craters in particular stymied tank support of the Red Beach forces by the light tanks of the 193rd Tank Battalion when the lead M3 light tank became partially submerged in a shellhole and blocked passage of all the vehicles behind it.
