The Battle of Sansapor (Operation Globetrotter) was an amphibious landing and subsequent operations around Sansapor, Dutch New Guinea on the Vogelkop Peninsula during World War II.

Admiral William Fechteler's Attack Force (Task Force 77) was to have a D-Day groupment comprising 11 destroyers, 5 APDs, 16 LCIs, 3 rocket LCIs, 8 LSTs, 4 PCs, and 1 ATF. A Covering Force (Task Force 78), consisting of 1 heavy cruiser, 2 light cruisers, and 9 destroyers under the command of Admiral Russell Berkey, was to be available for support fire if needed.

In preparation for Operation Typhoon (code name for the US Army landings on the Vogelkop Peninsula), on 17 June 1944, S-47, under Lieutenant Lloyd V. Young, sailed from the Admiralty Islands for Waigeo, with the mission to insert elements of the Alamo Scouts, Allied Intelligence Bureau agents, terrain experts of the Fifth Air Force, and hydrographic survey men of the VII Amphibious Force. The reconnaissance force landed near Sausapor-Mar on 23 June where the party spent the week surveying the region. As a result of the both ground and aerial reconnaissance the assault landing was diverted to land 55 miles (89 km) northeast of Sorong.

On 30 June 1944, Operation Typhoon landed at Sansapar (Green Beach), Mar (Red Beach), Middelburg Island and Amsterdam Island. In charge of the Operation Typhoon ground forces was Major General Franklin C. Sibert, commanding general of the 6th Infantry Division. General Sibert was to command an organization designated the TYPHOON Task Force, which comprised the 6th Division (Reinforced), less the 20th Regimental Combat Team. Combat units for the D-Day echelon of the TYPHOON Task Force were the 1st Infantry Regiment, the 1st Battalion, 63d Infantry Regiment, the 1st Field Artillery Battalion, the 6th Cavalry Reconnaissance Troop, a company of the 6th Engineers, and four antiaircraft batteries. All of the landings ultimately proved to be unopposed and it was not until 16 August that elements of the Japanese 35th Division were able to reach the area of the landings. By 31 August the 1-63rd Infantry had killed 155 Japanese and taken 42 prisoners. The American regiment lost only 3 men killed and 4 wounded. The 1st Infantry, on the west flank, killed 197 Japanese and captured 154, while losing only 4 men wounded itself. The 6th Cavalry Reconnaissance Troop, during its series of far flung patrols, killed 42 Japanese and captured 5 others. Total battle casualties for the TYPHOON Task Force from 30 July through 31 August were 14 killed, 35 wounded, and 9 injured. Japanese losses during the same period were estimated to be 385 killed and 215 captured.
