 Cooper, Francis H. [LtCol 1stAATB]

 

 

 At this time, moreover, an order from the Secretary of the Navy made it necessary to reduce the size of the landing force by withdrawing about 500 Marines who had not yet reached their 18th birthday. They were transferred to the 1st Armored Amphibian Tractor Battalion, which was to be left behind at Kobe when the Division embarked for Inchon.

This unit had been organized at Camp Pendleton in accordance with a directive from the Commandant. It was found necessary, however, to transfer most of its combat-ready men to the 1st Tank Battalion in order to bring that outfit up to full strength. The tank battalion was given priority because its vehicles would be used throughout the operation while the armored amphibians might be employed only occasionally. As a consequence, the 1st Armored Amphibian Tractor Battalion left San Diego with new personnel lacking in the skills to make it fully combat ready.

Lieutenant Colonel Francis H. Cooper, the commanding officer, recommended at Kobe that the unit be withheld from action until drivers, gunners, and maintenance crews could be properly trained. General Smith and his staff concurred, having learned that a trained Army unit, Company A of the 56th Amphibian Tractor Battalion, could be made available. Orders were given for Cooper’s battalion to remain at Kobe, therefore, with the 17-yearold Marines attached.
