The GADSDEN area of operation was some thirty kilometers northwest of Tay Ninh, in the vicinity of Lo Go and Xom Gina, South Vietnamese villages on the Cambodian border. (Map 9) The terrain is generally flat and the vegetation ranges from rice fields to triple-canopy jungle. During the operation grasslands in the area were as tall as six feet. There was some heavy mud in paddy areas, but most of the previously flooded positions had dried, thus facilitating overland movement. Weather was favorable for the operation.
