 In an effort to bolster the strength of White's 11th MSF Company, a mortar platoon of about 35 Montagnard CIDG was sent from Khâm Đức to reinforce the small garrison at Ngok Tavak during the final days of April.It was intended that the Montagnards would provide local security for the garrison when the 11th MSF Company was out on patrol.Mistrust developed between White's men and the Montagnard soldiers, because the latter were known to contain VC infiltrators.
