10 March - The attack was continued at 0800 with the same 
scheme of maneuver.  No artillery or naval gunfire preparations were fired.  The 
3d Bn, 9th Marines pushed down to the beach and turned southward to sweep 
to the division right boundary.  This battalion was hindered during the day by 
hostile small arms fire delivered from the high ground to its flank and rear.  The 3d 
Bn, 21st Marines continued its attack against the enemy pocket to its front using 
tanks, but made little progress.  Difficulty was experienced in getting 
replacements to work properly with tanks.  The 2d Bn, 9th Marines continued to 
mop up enemy elements in its immediate vicinity and little advance was made.  
This battalion was now badly depleted.  The 21st Marines changed direction and 
started a sweep toward the north.  The 1st Bn, 21st Marines, by patrols, had 
established that no enemy were in the beach area and advanced generally 
north with their right flank on the cliff overlooking the beach.  The 2d Bn, 21st 
Marines were still unable to advance its left flank because of hostile fire from the 
5th Marine Division zone of action, although it kept its right flank in contact with 
the 1st Bn, 21st Marines.  At 1500 the 21st Marines, reported all organized 
resistance eliminated in the zone of action of the 1st Bn, 21st Marines and patrols 
were dispatched by that battalion through its zone of action in rear of the line to 
mop-up any remaining enemy elements.  Just prior to noon, information was 
received from Corps that the 4th Marine division was advancing rapidly toward 
the coastline and had reported their left flank 700 yards in advance of the 3rd 
Marine Divisions right flank.  Permission was secured to move the division reserve 
battalion, 1st Bn, 9th Marines to an assembly area in rear of the left flank of the 
4th Marine Division for a flanking attack through the gap to the northeast to 
effect a juncture with the 3d Bn, 9th Marines, thereby localizing remaining enemy 
resistance in the 9th Marines zone of action.  The 1st Bn, 9th Marines was moved 
out early in the afternoon and arrangements were made with the 23d Marines to 
have them guided into an assembly area in rear of the left flank of the 4th 
Marine Division.  On arrival of the battalion in its assembly area for the attack, it 
was found that the gap was only about 200 yards and the 4th Marine Division left 
flank was not as far forward as it had reported and much further to the right, 
being actually some four or five hundred yards from the boundary between 
divisions.  The 1st Bn, 9th Marines launched its attack, however, in a column of 
companies at 1535.  The battalion made little advance, being taken under 
enemy small arms fire from positions on the ridge generally in TAs 201-J and 202-
K.  During the entire advance down the northeast slopes to the coast, the 4th 
Marine Division constantly erroneously reported the location of its left flank, 
invariably placing it forward, and usually further to the left, of its actual location.  
As the advance progressed, the 4th Marine Division gradually pulled its left flak 
away from the division boundary with the result that a considerable part of the 
operations of the 9th Marines were carried on in the 4th Marine Division zone of 
action.  The 2d Bn, 9th Marines was disengaged during the afternoon and by 
1800 had closed in its assembly area in division reserve I the vicinity of 
MOTOYAMA village.  Steps were immediately taken to provide this battalion with 
replacements and equipment.  At 1800 the situation was as shown in Enclosure B 
(20), Situation at 1800, 10 March.
