122 • THE ROAD TO VICTORY: From Pearl Harbor to Okinawa
The 2nd Division, USMC
At the time of Galvanic the 2nd Division
numbered around 20,000 men, composed of
three infantry regiments, the 2nd, 6th, and 8th
(the USMC traditionally refer to their regiments
simply as "Marines")- An average regiment
would comprise about 3,500 officers and men,
and would have three rifle battalions consisting
of three rifle companies, one weapons company,
and one HQ company.
There were additional organic units within
the division. A tank battalion of three companies
of three tank platoons was using the Sherman
M4-A2 medium tank. These were ideal for use
against the Japanese in the Pacific where they
completely outclassed the Japanese "Ha-Go"
tanks. There was also a medical battalion and
the amphibian tractor battalion who were the
first to use the improved LVT-2 tractor universally
known as the amtrac. The Marines at Tarawa,
unlike those who fought at Guadalcanal, had
modern infantry weapons including Garand M-i
semi-automatic rifles, Browning automatic rifles,
and portable flame-throwers.
The US Navy
From the time of their embarkation in
Wellington, New Zealand, on November 1, until
they left the line of departure for the invasion
beaches, the Marines of Holland Smith's
V Amphibious Corps (VMAC) were the
responsibility of the US Navy. The invasion
force - Task Force 54 (TF-54) - was subdivided
into two groups: the Northern Attack Force
(TF-52) under Rear-Admiral Richmond Kelly
Turner, which was to secure the island of Makin
to the north; and the Southern Attack Force
(TF-53) under Rear-Admiral Harry Hill, which
would take Tarawa Atoll.
The fire support group, under Rear-Admiral
H. F. Kingman, comprised the battleships
Tennessee, Maryland, and Colorado; the heavy
cruisers Portland and Indianapolis; the light
cruisers Mobile, Birmingham, and Santa Fe\ and
the destroyers Bailey, Frazer, Gansevoort,
Meade, Anderson, Russell, Ringgold, Dashiell,
and Schroeder. The three battleships of the group
were semi-obsolete ships that had been salvaged
from the mud of Pearl Harbor after the 1941
attack. However, they still packed a hefty punch
with their 14m and i6in guns, and were ideally
suited to provide offshore bombardments.
For air cover, aerial bombing, and strafing
during the operation, three aircraft carriers,
the Essex, Bunker Hill, and Independence, of
Rear-Admiral Montgomery's TF-50-3 would
accompany the Southern Attack Force.
THE JAPANESE FORCES
The battle for Tarawa would see the first
confrontation between the US Marines and
Japan's Special Navy Landing Force (SNLF) -
sometimes referred to as the "Imperial
Marines." The SNLF could trace its origins to
the earliest days of the Imperial Japanese Navy
(IJN) when they were developed as small
infantry units attached to naval ships. Over the
years, however, they evolved into much larger
combat units of highly trained and specialized
amphibious infantry. In 1941 they had
spearheaded the invasions of Guam, Wake
Island, and the Solomons.
On Betio Island, Rear-Admiral Shibasaki
commanded the 3rd Special Base Defense
Force (formerly the 6th Yokosuka SNLF),
the Sasebo 7th SNLF, the 111th Construction
Unit, and a detachment of the 4th Fleet
Construction Department; in all around 5,000
men. Because of the small area of the island, a
considerable amount of which was taken up
by the airfield and its facilities, Shibasaki
concentrated his efforts on defeating the
