1 April 1945: Operation "TEN-I-GO" (Heaven Number One) - The attack on the U. S. Invasion Forces at Okinawa:
SAKAWA and DesRon 11 are attached to Vice Admiral Ito Seiichi's (former CO of HARUNA) Second Fleet for the attack on the U. S. Invasion Forces at Okinawa by YAMATO and her escorts, but there is no fuel available for SAKAWA and her destroyers.

6 October 1945:
Palaus. USS CARROLL (DE 171) patrols the smaller islands of the Palau group searching for by-passed Japanese garrisons and prisoners of war. The 1,339 Japanese Army troops stationed on the islands first learn of the surrender of Japan when search parties go ashore. The surrender of four small islands in the southern Palaus, Sonsorol, Fanna, Merir and Tobi to the Island Commander, Peleliu is signed on CARROLL's deck.
21 and 29 October 1945:
1 December 1945:
CARROLL furnishes supplies and supervises the evacuation of the islands by the Japanese. All troops on the islands are removed by SAKAWA.
SAKAWA is officially assigned to the Repatriation Service as a transport.
December 1945 - February 1946:
SAKAWA makes repatriation runs to New Guinea, Korea and other locations to bring back former Japanese troops for demobilization.
25 February 1946:
SAKAWA is transferred to Yokosuka and turned over to the U. S. Navy. A crew goes aboard SAKAWA to prepare the rat-infested hulk for a voyage. A Japanese bucket brigade works 36 consecutive hours bailing foul water from her bilges.
18 March 1946:
SAKAWA departs Yokosuka for Eniwetok with a U. S. Navy crew of 165 men and officers under LtCdr Jesse E. Miller. Our American crew replaced the 1,100 Japanese crewmen who had been aboard during the war. Eleven Japanese officers remain aboard to teach the Americans how to run the ship. SAKAWA is accompanied by battleship NAGATO that is also under an American crew.
28 March 1946:
Oil tanker NICKAJACK TRAIL, enroute to Yokohama, is diverted to refuel SAKAWA and NAGATO, but runs aground on a reef and is lost.
300 miles from Eniwetok. SAKAWA breaks down and goes dead in the water. NAGATO sets a tow-line to SAKAWA, but then NAGATO blows out a boiler and runs out of fuel. Both ships are stopped in bad weather. NAGATO's crew radios to Eniwetok for help, then roll in the seas waiting for tugs to take them in tow.
30 March 1946:
USS TENINO (AT-115) and another tug arrive from Eniwetok and take SAKAWA and NAGATO under tow. NAGATO is towed at 1 knot.
1 April 1946:
SAKAWA is towed into Eniwetok, four days ahead of NAGATO.
Eniwetok. Five American sailors sabotage SAKAWA while she lay at anchor. Their motive is to put SAKAWA out of commission so they can be relieved of duty aboard the filthy warship. They demobilize the ship's fuel system by removing the pressure line to the overspeed trip valves. Sand is poured into the oil and water pumps. They smash gauges, tachometers and fuel oil manifold valves. High pressure steam lines are cut. Repairs take four days. Rather than being relieved of duty, the five sailors are brought up on charges.
SAKAWA steams 200 miles from Eniwetok to Bikini Atoll.
1 July 1946: Operation "Crossroads":
The bomb misses NEVADA. The detonation of the Able bomb occurs 490 yards above and slightly to starboard of SAKAWA's stern. SAKAWA burns fiercely for twenty-four hours. The force of the blast crushes her superstructure, damages her hull and breaches her stern. She begins to flood aft.
2 July 1946:
Bikini. SAKAWA and AGATO are target ships in the atomic bomb air burst detonation test "Able". NAGATO is joined by American target battleships USS ARKANSAS (BB-33), NEW YORK (BB-34), NEVADA (BB-36), PENNSYLVANIA (BB-38) and other ships. SAKAWA is moored off the port quarter of NEVADA, the target ship for the test. On board SAKAWA are pigs, monkeys, goats, chickens, guinea pigs, rats and mice, in cages or tied securely. The animals are to be tested for radiation after the bomb is dropped.
Fleet tug USS ACHOMAWI (ATF-148) attempts to tow SAKAWA to a beach to save it from sinking. After she attaches a tow cable to SAKAWA, the cruiser’s bow rises up and she keels over 85 degrees to port. SAKAWA begins to sink by the stern. Several attempts are made before the tow cable is finally cut. At 1042, SAKAWA capsizes and sinks by the stern. About 700 feet of the cable goes to the bottom of Bikini Lagoon with her. 
 Piglet No. 311, weighing 50-lbs., is found swimming in the radioactive waters and rescued. She is sterile, but grows to 600 lbs over the next several years.

Special thanks for assistance in preparing this TROM go to Mr. Fred Herschler, former RM/2, USN, a crewman aboard Bikini-bound NAGATO. Thanks for assistance also go to "Adm. Gritter" of the Netherlands and Tony Tully, Randy Stone and John Whitman of the United States.
