Lieutenant Colonel, U.S. Marine Corps 7th Marines, 1st Marine Division Date of Action: May 10 - 12, 1945 Citation: The Navy Cross is presented to James M. Masters, Lieutenant Colonel, U.S. Marine Corps, for extraordinary heroism as Executive Officer of the Seventh Marines, First Marine Division, in action against enemy Japanese forces during the assault on Dakeshi Ridge, Okinawa, Ryukyu Islands, from 10 to 12 May 1945. On 10 May, when the advance of the Regiment was checked by a strong hostile force, Lieutenant Colonel Masters unhesitatingly went forward of the front lines on reconnaissance and obtained information concerning the Japanese and unfamiliar terrain which enabled a successful attack to be made the following day. On 11 May, he established an advanced observation post in the only possible position on the front lines from which the attack that day could be observed and directed and, despite unusually heavy casualties at the post from intense enemy mortar and small-arms fire, continued to man it and report information vital to the capture of desperately defended Dakeshi Ridge, Moving the observation post forward again on 12 May, he advanced under intense hostile fire to the Ridge before that ground had been completely seized by assault troops and, although the Japanese continued to inflict heavy casualties on his force, persevered in his mission to observe the enemy and terrain, thus securing information which aided materially in the formulation of successful plans for continuing the attack. His inspiring leadership, courage and unremitting devotion to duty throughout were in keeping with the highest traditions of the United States Naval Service.

Marianas Operation /Operation Tatteralls: Battle of Tinian (1944)
From Month/Year
July / 1944
To Month/Year
August / 1944
Description The 2nd and 4th Marine Divisions landed on 24 July 1944, supported by naval bombardment and artillery firing across the strait from Saipan. A successful feint for the major settlement of Tinian Town diverted defenders from the actual landing site on the north of the island. The battleship Colorado and the destroyer Norman Scott were both hit by 6-inch (150 mm) Japanese shore batteries. Colorado was hit 22 times, killing 44 men. Norman Scott was hit six times, killing the captain, Seymore Owens, and 22 of his seamen. The Japanese adopted the same stubborn resistance as on Saipan, retreating during the day and attacking at night. The gentler terrain of Tinian allowed the attackers more effective use of tanks and artillery than in the mountains of Saipan, and the island was secured in nine days of fighting. On 31 July, the surviving Japanese launched a suicide charge.
The battle saw the first use of napalm in the Pacific. Of the 120 jettisonable tanks dropped during the operation, 25 contained the napalm mixture and the remainder an oil-gasoline mixture. Of the entire number, only 14 were duds, and eight of these were set afire by subsequent strafing runs. Carried by Vought F4U Corsairs, the "fire bombs", also known as napalm bombs, burned away foliage concealing enemy installations.
Aftermath
Japanese losses were far greater than American losses. The Japanese lost 8,010. Only 313 Japanese were taken prisoner. American losses stood at 328 dead and 1,571 wounded. Several hundred Japanese troops held out in the jungles for months. The garrison on Aguijan Island off the southwest cape of Tinian, commanded by Lieutenant Kinichi Yamada, held out until the end of the war, surrendering on 4 September 1945. The last holdout on Tinian, Murata Susumu, was not captured until 1953.
After the battle, Tinian became an important base for further Allied operations in the Pacific Campaign. Camps were built for 50,000 troops. Fifteen thousand Seabees turned the island into the busiest airfield of the war, with six 7,900-foot (2,400 m) runways for attacks by B-29 Superfortress bombers on targets in the Philippines, the Ryukyu Islands and mainland Japan, including the atomic bombings of Hiroshima and Nagasaki.
Four 1000-bed hospitals were planned and located in preparation for the invasion of Japan. None were actually built, as the Japanese surrendered after the atomic bombs were dropped, which thus ended the need for the hospitals.
