The lull was tactically unfortunate because enemy units moved south into the
sector to the division's front in force despite efforts by the Marines to, "patrol vigorously

positions." ("Spike" Selmyhr stated that he hated the term "maintain contact," "because
what it really meant was that we moved toward their positions until we received fire, and
then immediately withdrew to report where it came from.") One enemy unit was the 2nd
NKPA Division, Ill Corps. This unit fortified Hill 673, though some fortifications already
existed there, and put in many mortar emplacements. It would take flamethrowers,
satchel charges, grenades, tanks, rifles, automatic-weapons, and Marine blood to get

North Korean Army [Division, actually] would be annihilated here on 673 and Ridgeline

patrol of the 7th Marines near Hill 673, the patrol would withdraw and call in supporting
