Around 12:30 a message arrived that some of the defenders were making their way across the sandbars from the extreme eastern end of the islet to Bairiki, the next islet over. Portions of the 6th Marine Regiment were then ordered to land on Bairiki to seal off the retreat path. They formed up, including tanks and pack artillery, and were able to start their landings at 16:55. They received machine gun fire, so aircraft were sent in to try to locate the guns and suppress them. The force landed with no further fire, and it was later found that only a single pillbox with 12 machine guns had been set up by the forces that had been assumed to be escaping. They had a small tank of gasoline in their pillbox, and when it was hit with fire from the aircraft the entire force was burned. Later, other units of the 6th were landed unopposed on Green Beach, north (near Red Beach 1).
