_The Japanese garrison on Betio conducts pre-battle training._]

The Japanese garrison on Betio on D-Day consisted of the _3d Special

Base Force_ (formerly the _6th Yokosuka Special Naval Landing Force_),

the _7th Sasebo Special Naval Landing Force_ (which included 200 NCOs

and officers of the _Tateyama Naval Gunnery School_), the _111th

Pioneers_, and the _4th Construction Unit_, an estimated grand total of

4,856 men.

All crew-served weapons on Betio, from 7.7mm light machine guns

to eight-inch naval rifles, were integrated into the fortified

defensive system that included 500 pillboxes, blockhouses, and other

emplacements. The basic beach defense weapon faced by the Marines

during their landings on the northern coast was the M93 13mm, dual

purpose (antiair, antiboat) heavy machine gun. In many seawall

emplacements, these lethal weapons were sited to provide flanking

fire along wire entanglements and other boat obstacles. Flanking fire

discipline was insured by sealing off the front embrasures.

Admiral Shibasaki organized his troops on Betio for “an overall

decisive defense at the beach.” His men fought with great valor. After

76 hours of bitter fighting, 4,690 lay dead. Most of the 146 prisoners

taken were conscripted Korean laborers.

Only 17 wounded Japanese surrendered.

_D-Day at Betio,_

_20 November 1943_

The crowded transports of Task Force 53 arrived off Tarawa Atoll

shortly after midnight on D-Day. Debarkation began at 0320. The captain

of the _Zeilin_ (APA 3) played the Marines Hymn over the public address

system, and the sailors cheered as the 2d Battalion, 2d Marines,

crawled over the side and down the cargo nets.

At this point, things started to go wrong. Admiral Hill discovered that

the transports were in the wrong anchorage, masking some of the fire

support ships, and directed them to shift immediately to the correct

site. The landing craft bobbed along in the wake of the ships; some

Marines had been halfway down the cargo nets when the ships abruptly

weighed anchor. Matching the exact LVTs with their assigned assault

teams in the darkness became haphazard. Choppy seas made cross-deck

transfers between the small craft dangerous.

Few tactical plans survive the opening rounds of execution,

particularly in amphibious operations. “The Plan” for D-Day at Betio

established H-Hour for the assault waves at 0830. Strike aircraft from

the fast carriers would initiate the action with a half-hour bombing

raid at 0545. Then the fire support ships would bombard the island from

close range for the ensuing 130 minutes. The planes would return for a

final strafing run at H-minus-five, then shift to inland targets as the

Marines stormed ashore. None of this went according to plan.

The Japanese initiated the battle. Alerted by the pre-dawn activities

offshore, the garrison opened fire on the task force with their

big naval guns at 0507. The main batteries of the battleships

_Colorado_ (BB 45) and _Maryland_ commenced counterbattery fire almost

immediately. Several 16-inch shells found their mark; a huge fireball

signalled destruction of an ammunition bunker for one of the Japanese

gun positions. Other fire support ships joined in. At 0542 Hill ordered

“cease fire,” expecting the air attack to commence momentarily. There

was a long silence.

The carrier air group had changed its plans, postponing the strike

by 30 minutes. Inexplicably, that unilateral modification was never

transmitted to Admiral Hill, the amphibious task force commander.

Hill’s problems were further compounded by the sudden loss of

communications on his flagship _Maryland_ with the first crashing salvo

of the ship’s main battery. The Japanese coastal defense guns were

damaged but still dangerous. The American mix-up provided the defenders

a grace period of 25 minutes to recover and adjust. Frustrated at every

turn, Hill ordered his ships to resume firing at 0605. Suddenly, at

0610, the aircraft appeared, bombing and strafing the island for the

next few minutes. Amid all this, the sun rose, red and ominous through

the thick smoke.
