(AM–274: dp. 945 (f.); l. 184’6”; b. 33’; dr. 9’9”; s. 15 k.; cpl. 104; a. 1 3”, 4 40mm.; cl. Admirable)

 

The first Pinnacle (AM–274) was laid down by the Gulf Shipbuilding Corp., Chickasaw, Ala., 1 February 1943; launched 11 September 1943; sponsored by Mrs. Francis W. Osborn; and commissioned 24 May 1944; Lt. Joseph B. Williams in command.

 

Following shakedown, Pinnacle joined MinRon 11 and sailed, 24 July, for the Mediterranean. She arrived at Mers-el-Kebir 10 August, crossed to southern France 10 days later and on the 27th began her first minesweeping operation off St. Tropez. Shifting east with units of MinDiv 32 in September, she cleared a fire support channel from Cape Martin, France, to Bordinghera, Italy. There into late October, she suffered no damage from German shore batteries and on the 23rd sailed back to Toulon, thence to Bizerte, whence she steamed to Cagliari, Sardinia. Between 25 November and 10 January 1945, she swept in the Gulf of Cagliari with only one interruption, an escort run to Palermo in December.

 

From Sardinia, Pinnacle returned to Palermo, whence, with Catoctin (AGC–5) she steamed to Istanbul. Arriving 25 January, she entered the Black Sea the next day, sweeping in shallow waters ahead of the AGC. Continuing on to Sevastopol and Yalta, she supplied guards for the Yalta Conference, and on 13 February got underway for Sicily for repairs. She resumed sweeping off Sardinia in early March, interrupted operations toward the end of the month for a run to Malta, and on the 31st departed Sardinia for Palermo, Oran, and the United States.

 

Arriving at Norfolk 5 May, she sailed for the west coast 5 July, mooring at San Pedro on the 26th. In mid-August she moved on to Pearl Harbor, thence to the Marianas, Okinawa, and Japan for minesweeping operation “Skagway”.

 

Engaged in clearing the shipping lanes of the East China Sea-Ryukyu area, 27 October–9 November, Pinnacle shifted to Formosa and the Pescadores at mid-month and continued to operate there until 22 December when she put into Shanghai. Departing Shanghai 21 January 1946, she steamed back to Japan, thence to the Marianas, and on 18 March, arrived at San Pedro.

 

In July Pinnacle headed west again. Arriving at Subic Bay, P.I., 14 September, she decommissioned 9 October 1946 and remained in reserve there until 15 June 1948 when she was transferred, on a permanent basis, to the Nationalist Chinese Navy. Struck from the U.S. Navy List 13 July 1948, Pinnacle, renamed Yung-Hsiu (MSF–48), patrols the coast and off-shore islands of Taiwan into 1970.

 

Pinnacle (AM–274) earned 2 battle stars during World War II.
