The Battle of Angaur: A Costly Pacific Campaign Historians Often Call Unnecessary
Fought over a tiny coral island, the Battle of Angaur was a brutal 36-day struggle in late 1944. While American forces secured the island to build airfields, the operation was delayed by landing craft shortages, rendering the resulting airstrips largely irrelevant to the critical Philippines campaign that followed.
The battle for Angaur, a small coral island just 3 miles long, was part of the broader Operation Stalemate II. Japanese forces, commanded by Major Ushio Goto, employed a new 'defense in depth' strategy. Instead of traditional banzai charges, they allowed American troops to land, then funneled them into fortified inland positions like the formidable Romauldo Hill. This terrain, honeycombed with caves and bunkers, became a microcosm of the intense fighting seen on nearby Peleliu.
Major General Paul J. Mueller’s 81st Infantry Division faced stiff resistance, particularly at a location known as 'the Bowl.' After repeated failed frontal assaults, American forces eventually neutralized the Japanese positions by using bulldozers to seal cave entrances. The fighting was characterized by sniper fire, booby traps, and the use of flamethrowers and explosives. Major Goto was killed on 19 October 1944, and the island was declared secure by 22 October, though the cost to the 81st Infantry Division was exceptionally high.
The strategic value of the operation remains a subject of historical debate. Admiral William F. Halsey, Jr. had argued against the invasion, and many historians agree that the primary outcome was not strategic gain, but the combat experience acquired by the 81st Infantry Division. While Seabees did construct an airstrip for B-24 Liberator bombers, the delay in the operation meant it was not ready in time to support the start of the Philippines campaign in October 1944.
The human toll was significant, with the 322nd Regimental Combat Team sustaining 80% of the American casualties on Angaur. Many of these injuries were head wounds caused by accurate sniper fire. Ultimately, only about 52% of the 81st Infantry Division's casualties during Operation Stalemate II were deemed fit enough to return to duty, highlighting the brutal nature of the island-hopping campaign.
