Marines in World War II Commemorative Series By Captain John C. Chapin U.S. Marine Corps Reserve (Ret) [Sidebar ( page 5 ):] Department of Defense Photo (USMC) A412992 The origins of this division lay in the activation of the 2d Marine Brigade as part of the Fleet Marine Force on 1 July 1936. A year later the brigade deployed to Shanghai, China, returning in 1938 to San Diego, California. On 1 February 1941, the unit was redesignated as the 2d Marine Division.

The 2d Marine Division
The 2d Marine Division
This 2d Marine Division shoulder patch was worn on Saipan. Designed and approved in late 1943, the insignia is in the official Marine Corps colors of scarlet and gold. The insignia displays a spearhead-shaped scarlet background with a hand holding aloft a lighted gold torch. A scarlet numeral “2” is superimposed upon the torch, and the torch and hand are encircled by five white stars in the arrangement of the Southern Cross constellation; under this the division’s first World War II combat took

The 4th Marine division
The 4th Marine division
Worn on Saipan, it had a gold “4” on a scarlet background, the official colors of the U.S. Marine Corps. This emblem was designed by SSgt John Fabion, a member of the division’s public affairs office before the Marshalls campaign. His commanding officer was astonished to find that, when the division attacked Roi islet in Kwajalein Atoll in the Marshall Islands (January 1944), the layout of the runways on the Japanese airstrip there were “an exact replica.” [Sidebar ( page 7 ):] This division, be

The Army 27th Infantry Division
After the division’s struggle on Saipan, it went on to the battle for Okinawa in April 1945, and then to the occupation of Japan in September 1945. The final chapter came in December 1946 when the 27th Infantry Division was deactivated. [Sidebar ( page 10 ):] The training before Saipan was based on a new Table of Organization for the Marine divisions. Their size was reduced by 2,500 men to 17,465. The artillery regiments each lost one of its 75mm pack howitzer battalions, but the infantry retain

[Sidebar ( page 11 ):] The 10th Marines and the 14th Marines supported the 2d and 4th Marine Divisions respectively. They had each had a significant reorganization before Saipan. In early spring, the 5th Battalion in each changed its designation. They were redesignated the 2d and 4th 155mm Artillery Battalions, Corps Artillery, but administratively attached to the 10th and 14th Marines. Thus the 10th and 14th Marines each contained two 75mm pack howitzer battalions (1st and 2d), two 105mm howitz

D+8–D+15, 23–30 June
Complications of a serious nature arose in the execution of the battle plan for 23 June. The battalion of the 105th Infantry still had not cleaned out Nafutan Point; there were semantic and communications differences between the two Smith generals as to orders about who would do what and when; the 106th and 165th Infantry got all tangled up in themselves during a march to take over the center portion of the American lines and were too late to jump off in the attack, thus delaying the attacks of

Now Holland Smith turned his attention to operation plans to drive through the northern third of Saipan and bring the campaign to a successful, albeit a bloody, conclusion. His next objective line ran from Garapan up the west coast to Tanapag and then eastward across the island. Past Tanapag, near Flores Point, the 2d Marine Division would be pinched out and become the corps reserve. That would leave the 27th Infantry Division and the 4th Marine Division to assault General Saito’s final defenses

D+24, 9 July
It was to be the final day of a long, grueling campaign. The 6th and 8th Marines came down from the hills to the last western beaches, while the 4th Marine Division, with the 2d Marines attached, reached Marpi Point, the northern end of the island. There a final drama of horror was played out. Lieutenant Colonel Chambers watched, amazed: During this day as we moved along the cliffs and caves, we uncovered civilians all the time. The Jap soldiers would not surrender, and would not permit the civi

Saipan’s Legacy
Saipan’s Legacy
The campaign on Saipan had brought many American casualties, and it also heralded the kind of fighting which would be experienced in subsequent operations in the Central and Western Pacific in the days that lay ahead in the Pacific War. Holland Smith declared it “the decisive battle of the Pacific offensive” for it “opened the way to the home islands.” Japanese General Saito had written that “the fate of the Empire will be decided in this one action.” A Japanese admiral agreed, “Our war was lost
