"Yorktown"s second strike—utilizing the same aircraft—returned to Tulagi and began their attack at 12:10 on the Japanese ships, many of which were now at full steam and attempting to put distance between themselves and Tulagi harbor. The second strike hit and sank the minesweepers "#1" and "#2" and severely damaged "Tama Maru" northeast of Savo Island. Another Japanese seaplane was shot down by a U.S. dive bomber during the second strike. After four F4F-3/3A Wildcat fighters from "Yorktown" joined the strike, the fighters shot down two more Japanese floatplanes over Florida Island. The four U.S. fighters then strafed "Yūzuki", killing her captain and nine others of her crew, and causing moderate damage to the ship. Two or three other Japanese floatplanes were damaged in Tulagi harbor and their crews were killed.
