Battle of Surigao Strait The Battle of Surigao Strait was the southern action of the larger Battle of Leyte Gulf in which a United States Navy battle line under Rear Admiral Jesse B. Oldendorf interposed in the path of a Imperial Japanese Navy southern force on 25 October 1944, resulting in the sinking of the old battleship Yamashiro and the destruction or withdrawal of most Japanese units. The engagement combined torpedo attacks by Destroyer Squadron 54 and other destroyers, cruiser gunfire by units including USS Phoenix and USS Boise, and battleship salvos from vessels such as USS California and USS West Virginia, illustrating the interplay of surface, submarine and air power during the Philippine campaign.
Background and strategic context
In October 1944 the Imperial Japanese Navy mounted a complex plan, conceived by Isoroku Yamamoto's successors and naval staff including Matome Ugaki and Soemu Toyoda, to attack the Allied landings at Leyte Gulf by converging three separate forces: a northern force under Jisaburō Ozawa, a center force under Takeo Kurita, and a southern force under Shoji Nishimura and Kiyohide Shima. The southern force intended to pass through Surigao Strait to reach Leyte Gulf and attack transports supporting General Douglas MacArthur's Leyte invasion, as part of a broader Japanese attempt to disrupt United States Army and United States Navy operations and to relieve pressure on the Philippine campaign. Allied naval intelligence, including signals intercepts by Fleet Radio Unit Pacific (FRUPAC) and analysis by Admiral Chester W. Nimitz's staff, provided crucial warnings that enabled commanders such as Thomas Kinkaid and Raymond Spruance to position forces in the approaches to Leyte.
Forces and commanders
The Allied force in Surigao Strait was commanded tactically by Rear Admiral Jesse B. Oldendorf and operationally under Admiral Thomas Kinkaid of 7th Fleet, comprising battleships of Task Group 77.2 including USS West Virginia (BB-48), USS Maryland, USS Tennessee (though the exact roster included other older battleships), nine cruisers such as USS Portland and USS Minneapolis and 28 destroyers organized into squadrons like Destroyer Squadron 54 led by commanders including Rodgers→replace? (noting strict naming: individual destroyers like USS Leutze, USS Bennion), plus PT boats including PT-127-type boats and patrol aircraft from United States Army Air Forces and United States Navy carrier groups. The Japanese southern force under Vice Admiral Shoji Nishimura and accompanied by Rear Admiral Kiyohide Shima included the battleships Yamashiro and Fuso (though sources vary on Fuso's attachment), heavy cruisers such as Nachi and Ashigara, and multiple destroyers like Shigure. Naval leadership for the Japanese overall operation involved Soemu Toyoda and planners in Takagi?; center and northern forces were commanded by Takeo Kurita and Jisaburō Ozawa respectively.
Prelude and movements
As the Leyte landings began on 20 October 1944, Allied reconnaissance from units including USS Lexington and USS Essex carrier aircraft, submarines of Submarine Force and patrols from Task Group 38.1 tracked Japanese movements. On 24–25 October Shoji Nishimura steamed north through Surigao Strait with a battle line attempting a night passage; concurrently Takeo Kurita's center force moved through the Sibuyan Sea and San Bernardino Strait while Jisaburō Ozawa's carriers feinted in the Northern Leyte Gulf to draw away William Halsey's force. Allied destroyer squadrons deployed in successive lines and laid torpedo ambushes off Hinigaran Point and the strait entrances, while PT boats of Motor Torpedo Boat Squadrons staged forward reconnaissance and harassment sorties.
Battle actions and sequence
Just after midnight on 25 October Japanese formations entered the southern approaches and encountered American PT boats and destroyers; early torpedo attacks by destroyers including USS Bennion and USS Leutze inflicted damage and disorganized the Japanese column. Successive American destroyer torpedo strikes from units of Destroyer Squadron 54 helped slow and disable leading ships, after which cruisers such as USS Phoenix and USS Boise opened fire with radar-directed guns. The battle culminated when Oldendorf's battleline — comprising battleships including USS West Virginia, USS Maryland, and USS Tennessee — crossed the Japanese T and engaged with heavy salvoes guided by radar sets like SG radar and Mark 8 fire-control. The battleship Yamashiro was heavily damaged by combined torpedo and gunfire and eventually foundered; cruisers Nachi and Ashigara also suffered hits, and several destroyers were sunk or put out of action. Air strikes from carrier aircraft of Task Force 38 and patrol bomber forces contributed to the destruction and prevented effective Japanese withdrawal.
Aftermath and casualties
The engagement resulted in the loss of the battleship Yamashiro and multiple Japanese cruisers and destroyers, with heavy casualties among personnel including Admiral Nishimura, who perished when his flagship sank. Surviving elements of the southern force under Kiyohide Shima retreated and later joined remnants of other forces, but the Japanese fleet's ability to contest Allied sea control in the Philippines Campaign was gravely reduced. Allied losses were light comparatively: several destroyers and cruisers received damage, and there were aircraft losses from carrier strikes and patrols. The sinking of Yamashiro and destruction in Surigao Strait contributed to the larger defeat at Leyte Gulf, which marked one of the most consequential naval battles of World War II in the Pacific Ocean.
Analysis and significance
Surigao Strait is frequently cited as the last classic battleship-versus-battleship engagement and as an example of effective combined-arms use of destroyer torpedo attacks, cruiser gunfire, battleship salvos and naval aviation, drawing analysis from historians and naval analysts including Samuel Eliot Morison, John Toland, and postwar studies by U.S. Navy Bureau of Ships. The engagement demonstrated the decisive value of radar-directed gunnery, night-fighting doctrine developed from interwar and early-war experience, and the impact of signals intelligence from units like FRUPAC. Strategically, the defeat of the Japanese southern force eliminated a major component of the plan to disrupt the Leyte landings and contributed to the collapse of Japanese seaborne supply and reinforcement capabilities in the Philippines, hastening Allied liberation of the Philippines and helping secure the sea lines for subsequent operations toward Okinawa and the Japanese home islands. The battle remains a focal point in studies of naval warfare transitions from gunline engagements to carrier-dominated fleets and is memorialized in accounts by participants and in naval historiography.
