Although the left battalion area was the center of attention in the 1st Marines line early on 5 September, the far right sector was not entirely neglected either. Five minutes after their initial attack on Bunker, other Chinese units also lunged at the Hill 48A outpost, Stromboli. An estimated reinforced platoon, supported by three active machine guns on Hill 104, 850 yards to the north, employed submachine guns, rifles, and grenades in their attack. This battle lasted for nearly two hours, until the Chinese soldiers withdrew at 0240. There were no Marine losses. No tally or estimate was made on the number of enemy KIA or WIA. It was presumed that some of the Communists did become casualties since the three machine guns that had been chattering away to support the attacker’s ground action suddenly went silent after Marines called down mortar and artillery fire on the Hill 104 positions. The probes of 1st Marines positions at Bunker Hill and, to a lesser degree, at Stromboli were repeated in the 5th Marines right regimental sector. At almost exactly the same time Colonel Eustace R. Smoak’s regiment[216] was struck at five of its forward outposts. In the case of OP Gary, on the right, the enemy merely shelled the position for 40 minutes. Against the four other outposts, known as Allen, Bruce, Clarence, and Felix, the Chinese employed both fire and assault troops. (See Map 12.) At Felix the action had begun at 0130, a half hour later than at the adjacent outposts. The difference was probably due to a C/1/5 ambush[217] which had engaged an enemy force operating between Donald and Felix. After a brief five minute fire fight the Marines broke off the action, pulling back to Felix. The other three outposts, clustered to the left of the 3/5 sector, received the brunt of the enemy thrust which lasted for an hour and 20 minutes before the Communists withdrew. [216] Colonel Smoak had relieved Colonel Culhane on 15 August. [217] Although 1/5 (Lieutenant Colonel Alexander W. Gentleman) was the regimental reserve at this time, the regiment had assigned one company to 2/5, manning the right sector. [Illustration: MAP 12 K. WHITE COMBAT OUTPOSTS AND AMBUSH SITES 5TH MARINES SECTOR (Division Right) Early September 1952] Employing a squad against both Allen and Clarence, and sending a reinforced company against Bruce, the enemy alternately assaulted and shelled the positions until 0420, after which the Communist units policed the battlefield for casualties and withdrew to the north.
