Wasmuth (Destroyer No. 338) was laid down on 12 August 1919 at the Mare Island Navy Yard, Vallejo, Calif., designated DD-338 on 17 July 1920; launched on 16 September 1920, sponsored by Miss Gertrude E. Bennet, stepdaughter of Lieutenant Colonel R. H. Davis, USMC, an officer on duty at Mare Island; and commissioned on 16 December 1921, Comdr. W. P. Gaddis in command.

Wasmuth was fitted out at Mare Island until 27 February 1922, when she sailed for Richmond, Calif. to commence her shakedown cruise. Operating off Sausalito and Mare Island Calif., the new destroyer completed her trials on 11 March, putting into her builder's yard on that day for post-shakedown repairs.

She sailed for San Francisco on 1 May and calibrated her sound signal apparatus at that port until the 4th, when she shifted to San Pedro. Wasmuth then spent the next month operating in connection with battleship torpedo practices, a duty broken on 7 May by dispatch service to San Diego. Returning to that port from San Pedro on 8 June, she commenced preparations for decommissioning soon thereafter.

Placed out of commission at San Diego on 26 July 1922, Wasmuth remained in reserve for nearly eight years during the financially tight 1920's, when treaty restrictions and cuts in operating funds reduced the Navy's active seagoing forces. Recommissioned on 11 March 1930, Lt. Comdr. I. C. Sowell in command Wasmuth operated as a destroyer for the next decade participating in an intensive slate of tactical exercises and maneuvers, varying that routine with upkeep and training. She also operated with the Battle Force's Destroyer Flotilla 2 from the western seaboard into the Caribbean. Only for one brief period, in the autumn of 1934, was Wasmuth not fully active being then assigned to Rotating Reserve Squadron 10.

With the construction of newer, more heavily armed and far-ranging destroyers, the need for the old "flushdeckers" in their designed destroyer role diminished. While, of course, a great many of those World War I authorized ships lay in reserve on both coasts, the Navy was expanding as the 1930's had progressed and, in view of ominous developments in Europe and the Far East, was broadening its operational horizons. Aviation oriented and mine-warfare types of ships seaplane tenders and f ast minesweepers and minelayers were needed.

Accordingly, some of the old "flush-deckers" were converted to other roles. Wasmuth, a unit of the fleet in Hawaiian waters since the permanent basing of the ships there in April 1940, was among the Clemson class ships chosen for conversion to high-speed minesweepers of the Chandler-class.

Wasmuth reclassified as DMS-15 on 19 November 1940 underwent the metamorphosis at the Pearl Harbor Navy Yard. Retaining her full four-gun main battery and an antiaircraft battery of .50-caliber machine guns, as well as depth charge tracks, the ship lost her torpedo capability when minesweeping gear replaced her dozen 21-inch torpedo tubes.

Upon completion of that conversion at the Pearl Harbor Navy Yard on 5 April 1941, Wasmuth sailed for Palmyra Island and operated there until 19 April when she set course to return to Pearl Harbor. The high-speed minesweeper subsequently remained in Hawaiian waters until 10 June, when she sailed for the west coast of the United States.

Returning to Hawaii in early July, Wasmuth operated out of Pearl Harbor through the autumn of 1941, as tensions increased in the Far East with each passing day. She operated on local patrol and minesweeping exercises during that time, as the fleet maintained an intensive training schedule to enable it to be ready for the hostilities with Japan that most in higher echelons feared inevitable.

Those fears, however, were realized quite unexpectedly shortly before 0800 on 7 December 1941, planes from six Japanese aircraft carriers swept down upon the fleet units present at Pearl Harbor, in a surprise attack. Wasmuth among the ships in port that Sunday lay at buoys D-7 and D-7S inboard in a nest with three sister ships of Mine Division (MineDiv) 4: Trever (DMS-16), Zane (DMS-14), and Perry (DMS17), at the mouth of Pearl Harbor's Middle Loch and just off Pearl City.

Wasmuth went to general quarters at once, and Lt. (jg.) J. R. Grey in the absence of both the commander and executive officer assumed command of the ship. Within three minutes, her gunners had all of the 50-caliber Browning machine guns ready for action while the "black gang" below prepared the ship to get underway. Inside the nest, however, the high-speed minesweeper could only bring her aftermost machine guns to bear against the approaching planes.

Shortly after 0900, about midway through horizontal bomber attacks (carried out by Mitsubishi B5N bombers), Aichi D3A-1's (later code-named "Vals") began glide- and dive-bombing attacks on the ships and shore installations, kicking off the fourth phase of the raid. Those planes, coming from a westerly direction, proved to be good targets for the eager gunners in the minesweepers and minelayers moored in Middle Loch. Wasmuth's gunners ( who expended 6,000 rounds of .50-caliber ammunition that December morn) opened fire whenever the planes came within range. One man Seaman 1st Class James P. Hannon, was given credit for a "kill" shooting down an Aichi that crashed on Waipio Peninsula, near Middle Loch. The ship managed to score hits on several other planes as they came by.

Lt Comdr. L. M. LeHardy Zane's commanding officer and the senior officer present of MineDiv 4 ordered the ships to get underway, Trever leading the pack at 0932. Five minutes later, Lt. J. W. Leverton, Wasmuth's executive officer, arrived as his ship edged out of Middle Loch, and took command, relieving Lt. (jg.) Grey who had fought the ship since the outset of the attack. Shortly thereafter, Trever's commander reported on board too, since his own ship was steaming down the channel without him.

Proceeding out of her harbor herself soon thereafter, Wasmuth took up patrols off the channel entrance. Meanwhile, while the attack itself had ceased, jittery sailors, marines, and soldiers were not so sure. At sea, the forces searching for the retiring Japanese suspected the presence of enemy submarines real or otherwise.

At 1023, Wasmuth dropped one depth charge "on suspicious water" but came up with only a negative result. At 1036, the high-speed minesweeper dropped another depth charge, but only achieved the same result as the first attack nothing. Although it brought up "large quantities of oil," there was no wreckage.

Later that afternoon, Wasmuth and Zane swept the Pearl Harbor entrance channel before the former anchored at the coal docks when her sweep wire parted. After she retrieved the sweep gear, she headed back to the open sea, where her commanding officer, Lt. Comdr. J. L. Wilfong, reported aboard. Trever's commanding officer, Lt. Comdr. D. M. Agnew, rejoined his own ship at 1636. MineDiv 4 soon resumed its patrol operations.

Wasmuth operated in the Hawaiian chain between Johnston Island and Pearl Harbor into the spring of 1942. She departed Pearl Harbor on 31 May 1942, and escorted Convoy 4111 to San Francisco, Calif., reaching her destination on 10 June. Departing "Frisco" on the last day of July, Wasmuth returned to Pearl Harbor with Convoy 2113, arriving on 12 August.

Departing Pearl Harbor on the 14th, Wasmuth left Hawaii in her wake for the last time, bound for the Aleutians. Reaching Kodiak, Alaska, on 20 August, the high speed minesweeper spent the remainder of her career in those inhospitable northern climes as part of Task Force 8, performing screen and escort duties for the supply ships necessary to bear the "beans, bullets, and black oil" to that theater. In the course of her operations that autumn and winter, the ship visited such picturesquely named places as Women's Bay, Dutch Harbor, Chernofski, Nome, Kodiak, and Point Mush.

Two days after Christmas of 1942, Wasmuth was escorting a convoy through a heavy Alaskan storm when two depth charges were wrenched from their tracks by the pounding sea, fell over the side, and exploded beneath the ship's fantail. The blasts carried away part of the ship's stern and the ship began to founder; in the gale, the pumps could not make headway against the inexorably rising water below.

Despite the heavy sea, Ramapo (AO-12) came alongside the crippled and foundering Wasmuth in a display of seamanship and daring. For three and one-half hours, the tanker remained with the sinking high-speed minesweeper, battling the waves while proceeding with the ticklish business of transferring the latter's officers and men (134) and two passengers. After completing that heroic rescue, Ramapo pulled away; Wasmuth eventually sank early on 29 December. Her name was struck from the Navy list on 3 September 1943.

Wasmuth (DMS-15) received one battle star for her part in the defense of the Fleet at Pearl Harbor on 7 December 1941.
