Cavalry engaged in a fierce battle with a PAVN force vastly outnumbering them. C Company endured catastrophic casualties, but succeeded in driving the enemy from the area and inflicting hundreds of casualties to a PAVN regiment. Following Operation Paul Revere IV, 2nd Brigade engaged in Operation Thayer II, a search and destroy campaign in the Bình Định Province. When the campaign concluded in early 1967, the 1st Cavalry Division had destroyed two enemy regiments and inflicted more than 1500 enemy casualties. The 2nd Brigade distinguished itself next in Operation Pershing, which initiated on 13 February 1967. Operation Pershing was a massive search and destroy mission in the northern Bình Định Province, in which the 1st Cavalry Division committed all three of its brigades to the same area for the first time in Vietnam. In April 1967, while in support of Operation Pershing, 2nd Brigade conducted Operation Lejeune in the Marine-controlled Quảng Ngãi Province. The operation was conducted to free up Marines in the Quảng Ngãi area of operations and facilitate their movement further north. It was almost immediately apparent that the enemy in the Quảng Ngãi region was not prepared for the challenges posed by a brigade of air cavalry troopers. The enemy dispersed and hid, and only little and sporadic contact was initiated until 16 April 1967. Operation Lejeune concluded successfully on 22 April 1967, and the 2nd Brigade returned to the Bình Định Province to continue rooting out the deeply entrenched enemy forces there. On 21 January 1968, Operation Pershing was concluded. In 11 months of fighting the division engaged in 18 major battles and numerous minor skirmishes, inflicting over 7000 enemy casualties. Four 2nd Brigade soldiers, Specialist Fourth Class Charles Hagemeister, Specialist Fourth Class George Ingalls, Specialist Fifth Class Edgar McWethy and Specialist Fourth Class Carmel Harvey were awarded the Medal of Honor for their heroic actions in support of Operation Pershing. On 22 January 1968, the 1st Cavalry Division relocated to the Quảng Trị Province to participate in Operation Jeb Stuart. As a result of the division's relocation for Operation Jeb Stuart, it was in excellent position to respond to the Tet Offensive. On 31 January 1968 the PAVN and Vietcong conducted a widespread and well-coordinated assaults on towns and cities across South Vietnam. Thousands of PAVN/VC fighters overran the city of Huế, while five battalions of PAVN attacked Quang Tri City. 2nd Brigade's 1/5 Cavalry,
