Capturing such an important target would be a significant coup, and Norton sent an entire battalion to locate and destroy it. Although unable to find the actual headquarters, the American force came upon a major PAVN supply base containing several tons of food and supplies. On 6 February the ARVN 40th Regiment, 22nd Division, met a PAVN battalion 4 km north of English and routed it in a short, violent fight. Accompanying US advisers reported counting over 100 PAVN dead. Still able to strike back, however, early the next morning the PAVN mortared English, killing or wounding 52 soldiers and damaging 5 helicopters. Although the PAVN probed the perimeter, they did not follow up with a ground assault. An uneasy, five-day Têt truce began at 08:00 on 8 February. Unconfirmed reports still predicted a PAVN attack against English, during or immediately after the truce. Meanwhile, US reconnaissance units, both ground and air, venturing near the base, continued to draw fire. That afternoon an enemy force of unknown size attacked an American unit in the Mieu Mountains between English and Hammond. The 2nd Brigade pursued with two battalions but failed to make contact. Throughout these inconclusive engagements, General Norton impatiently waited at his new command post at Landing Zone Two Bits, 3 km south of English, for the truce to end. During Thayer II, which now had lasted about two and a half months before officially ending on 12 February 1967, he had steadily worn down the 3rd Division, driving its 2nd Regiment out of Bình Định Province and severely damaging its 18th and 22nd Regiments. Altogether, his troops had reported killing 1757 PAVN/VC, while 242 Americans were killed, and 947 wounded. Now they found themselves sitting idle, while the rest of the division either fled from their grasp or seemed prepared to strike back. Operations Thayer, Irving, and Thayer II displaced a large number of people in Bình Định Province. At the end of 1966, the province had 85 refugee camps with a reported population of 129,202. Additional people displaced by the war crowded into towns and villages or lived as squatters along Highway 1. About one-third of the 875,000 people of Bình Định were displaced in 1966 by the war. In some instances the displacement of people by the U.S. and South Vietnam was deliberate, forcing people to leave the Kim Son and An Lao valleys and declaring them free fire zones.
