"Open fire when targets are in range," 6th Battalion headquarters notified all guns at 6:30 a.m. One minute later, Midway's guns opened fire. A Kate erupted into flames and dove straight down. A second Kate crashed into the lagoon, missing the PT-boats. The remaining Kates struck Sand Island, destroying three oil tanks and setting fire to a seaplane hangar.
