USS John C. Butler (DE-339) was named after U.S. naval aviator John Clarence Butler (1921-1942), killed during the Battle of Midway in June of 1942.
Destroyer escorts fulfilled the primary role of convoy protection and fleet screening and proved more economical when compared to full-fledged destroyers (the necessity of war dictated quantity over capability at this point). The Butler-class was modestly-armed through a collection of weapons that included Dual-Purpose (DP) guns, Anti-Aircraft (AA) guns and sub-hunting depth charges. USS john C. Butler was herself outfitted with 2 x 5" (127mm) DP deck guns, 4 x 40mm Bofors AA guns, 10 x 20mm Oerlikon AA guns and 3 x 21" torpedo tubes. She also carried 8 x depth charge projectors, 2 x depth charge racks and 1 x "hedgehog" depth charge projector. With this armament suite, Butler could engage nearly all manner of enemy threat - whether they arrived by air, on the sea or under it.
USS John C. Butler's first notable actions were in the Battle of Leyte Gulf as part of the October 1944 Allied campaign to take back the Philippines. This included the Battle of Samar (October 25th) which pitted six American escort carriers, several destroyers and destroyer escorts against four Japanese battleships, six heavy cruisers, two light cruisers and some eleven destroyers. Kamikaze attacks were also part of the Japanese plan.
Beyond laying down a smoke screen, Butler attacked enemy warships with her torpedoes before engaging at shorter ranges with her deck guns. Much to the surprise of the Americans, the Japanese fleet began their retreat rather than risk more damage which protected the inbound Allied transports. Butler then remained on station to recover crew thrown into the water from the sinking of USS St. Lo, an escort carrier which took a kamikaze strike. The force returned to Pearl Harbor (with Butler escorting) and Butler made her way to Manus in mid-December. She was used to cover the landings at Luzon thereafter and, in January of 1945, her determined crew drove off a wave of kamikaze attacks. The vessel then took part in protecting the carrier force at Lingayen Gulf (South China Sea).
