There is one word that will explain why this unsupported Jap invasion got stopped in its tracks.[:D]
MARINES!
The Marines of the defense battalion were dug-in, in-depth starting at the edge of the beach with their heads up since there was no naval or air bombardment. The Marines were just waiting. They waited and waited and the waves of Jap barges got closer and closer. Fingers were twitching near triggers but they knew the plan so they waited. They even waited as the Jap soldiers from the first wave started jumping in the water 50 yards off the beach. All this time the Jap invasion transports were edging in since it seemed the silly Americans were asleep so lets get closer so we can unload quicker.
Just as the first Japanese soldiers emerged from the water, the order was given. COMMENCE FIRING! FIRE AT WILL! Since they waited, all the Marine weapons were now in range and able to fire. After two minutes the Japanese first wave ceased to exist except for a few individuals trying to hide behind their dead or dying buddies. The water at the edge of the beach was quickly turning red! The Jap second and third waves were nearing their drop-off points but they still did not realise the magnitude of the fire storm they were about to enter.
About this time a Marine Captain ordered his heavy CD guns to open fire on the enemy transports that were only 4000yards off shore. The crew of Battery Two were quickly rewarded with the sight of one of the transports just blowing up. At least a hundred Japanese soldiers were blown into the air, twirling like Autumn leaves as they fell into the bluegreen ocean.
It was now time to let the Army puke's who were hiding in the middle of the island to join the party. The Captain nodded to his Gunny. The Sgt picked up a phone and said "they landed right were we thought they would, your indirect anti-beach guns may commence firing, I will call with corrections as needed. Your guns assigned to the anti-ship mission may also open fire. The Jap transports have been sucked into point blank range. Good hunting!"
Well, you all know the rest of the story. The defenders were well supplied and thus had plenty of ammo. Since there was no heavy fire coming in from the Japs, they just kept firing and firing and the Japs just kept dying. The American guns needed water poured on them because the weapons were becoming red hot from the near constant firing. The Japs just kept coming and coming only to be mowed down time after time. (remember a new Shock Attack with each new landing) Maybe 5% of each wave would make it to the beach alive. With no heavy fire support the invasion was doomed and could not get more than a hundred yards off the beach.
A Japanese Private who was trying to dig a hole in the soft sand of the beach was heard to say "who ever planned this fiasco should be shot"! Five minutes later, as reinforcements arrived, the next Banzai charge was ordered and the Private started running up the body covered beach. He had run only 10 yards and was killed instantly by a 30cal Rifle slug thru the heart. Remember those Marines. Especially when not harassed by heavy fire, Marines don't miss!
