Last time when we left the USS Sway (AM-120), she had just arrived in Buckner Bay, Okinawa. Though the Battle of Okinawa was considered over, there was still a great deal of minesweeping to be done. The invasion of Japan was being planned, and a desperate enemy continued suicide tactics in hopes of driving down Allied morale and destroying assets needed for the invasion.

July 15, 1945.
Reported to C.T.G. 39.11an assigned to CTU 39.11.6 replacing USS Triumph (AM-323).
July 17, 1945.
1543—Under way to carry out Typhoon Plan X-ray in company with CTU 39.11.
The typhoon was a plan to move the vessels out of Buckner Bay to safety. Pacific typhoons could be extremely powerful. A typhoon in December 1944 had cost the Third Fleet three destroyers,146 aircraft, and 790 sailors dead or missing. Ships fare better at sea than in port, which is why even today large naval bases in the path of a hurricane or typhoon will still send all ships capable of doing so out to sea if a threat is imminent.
This particular typhoon, named Opal, was a Category 1 storm, and its maximum sustained recorded winds were only 75 miles per hour, which is barely strong enough to be categorized more than a tropical storm. Opal passed to the west of Okinawa and ultimately made landfall in Japan. The ships would remain at sea until the 21st.

As you can see, today was a relatively quiet day for the USS Sway; however, such was not the case for all ships that were serving in the area. The Japanese military had begun using kamikaze attacks before Okinawa but they had reached their peak during the battle here. By this point in the war they were few and far between but not nonexistent. My grandfather talked about them in an interview:
“We were assigned to ring patrol [a circle of ships around the island] to keep enemy aircraft, subs, and surface craft away from our landing craft and Marines/soldiers on the beaches. Four times on the ring patrol we were involved with kamikaze attacks; however, we were never hit, probably because we were not a prime target like the troop carriers and battleships.”
Looking at historical records, three of those attacks occurred on the date of the last entry. Two ships were damaged and one was sunk. The destroyer USS Callaghan (DD-792) was struck by a Yokosuka K5Y biplane on the starboard side, where one of its bombs penetrated the aft engine room. The destroyer flooded, and fires ignited the antiaircraft ammunition. She went down with 47 members of her crew. This was the last ship sunk by a kamikaze attack during the war.

With the last full month of the war coming to a close, the following month would see more minesweeping operations, a fourth kamikaze attack—and the use of a new weapon that would forever change the world.
