Bugara closed with them. The crew of the first vessel, a 64-gross register ton schooner at anchor, quickly abandoned ship as Bugara closed in, and Bugara′s gunners sank her. It had become too dark for Bugara to find the second vessel, so she cleared the area. On 6 August 1945, Bugara took station in the narrows of Samui Strait in the hope of finding more targets. Having misjudged the fathom curve by a few nautical miles and finding herself in shallow water, she headed back to safe water and soon found her first target of the day, a 125-gross register ton junk bound from Singapore for Bangkok with a cargo of rice. The captain of the junk proved reluctant to part with his Japanese flag, but was eventually persuaded to relinquish it. Bugara took off the junk's crew and sank her with gunfire. After also sinking a brand new coastal cargo ship with a gross register tonnage Bugara estimated at 30 — although the ship's papers gave it as 16.6 — and four more junks, Bugara sighted a submarine at 20:03 which turned out to be the British , a Royal Navy submarine also operating in the Gulf of Siam and investigating the four junks. Bugara decided to assist Sleuth in her search-and-destroy efforts and boarded and sank with gunfire two more vessels, a 26-gross register ton junk flying the Japanese flag and a 75-gross register ton schooner loaded with aviation gasoline which Bugara′s gunners set ablaze. After exchanging information with Sleuth′s crew, Bugara made a radar contact at 22:46 which came into sight. Bugara closed in on the vessel, a 60-gross register ton junk, firing a burst of 20-millimeter fire to grab her attention. The junk′s crew abandoned ship, leaving her with her sails up with a stiff wind blowing and making it difficult for Bugara to go alongside her. Despite this, Bugara brought her crew aboard, sent the junk to the bottom with the usual two shots, and then released the junk's crew near shore. 7–15 August 1945 Bugara sank two more coastal cargo ships on 7 August 1945. She sank the first, a new 26.5-gross register ton vessel flying the Imperial Japanese Navy ensign, at 07:50. The second, a slightly larger 28-gross register ton vessel loaded with rice bound for Singapore, became Bugara′s last victim of World War II. At 15:50, Bugara passed through floating wreckage, finding
