elements of a second, and two Army divisions, and in addition a new command structure. Although subordinate to III MAF, Provisional Corps, Vietnam, commanded by Army Lieutenant General William B. Rosson, had operational control of U.S. forces in Quang Tri Province and Thua Thien Provinces including the 3d Marine Division, the 1st Air Cavalry Division, and the 101st Airborne Division.*
These changes in command relationships and the arrival of the new Army divisions in northern I Corps had an effect upon the ANGLICO organization in the corps sector. Since 26 January, Marine First Lieutenant Pasquale J. Morocco headed the ANGLICO fire control party with the 1st Air Cavalry Division at Camp Evans. Prior to the establishment of Provisional Corps, Lieutenant Hatch, the I Corps Naval Gunfire Liaison officer, also doubled as the MACV (Forward) Liaison officer when that command was temporarily installed at Phu Bai under General Creighton W. Abrams in early February. He remained in that dual capacity until 10 March when Provisional (Prov) Corps came into existence and General Abrams returned to Saigon. On 16 March, Navy Lieutenant Dale W. Lucas became the Provisional Corps Naval Gunfire Liaison officer. At about the same time, Navy Lieutenant Warkenrin transferred from Hue to Camp Eagle outside of Phu Bai to head the shore fire control parry attached to the 101st Airborne Division. On 23 April, ANGLICO spotters called in a Marine close air strike in support of the 101st marking "the first time" during the war that non-Air Force personnel controlled a close air support mission for the division.31
Throughout the period from February through June 1968, the tempo of naval gunfire support increased throughout Vietnam with the bulk going to support U.S. and allied forces in I Corps. For example, in February, Navy ships off the coast of South Vietnam fired more than 94,000 rounds. Of this total, ANGLICO teams in I Corps controlled missions firing nearly 18,000 of those rounds, which did not include the missions fired in support of the 3d Marine Division along the DMZ. By June, while somewhat reduced from February, the U.S. Seventh Fleet fired more than 79,000 rounds in support of all forces, with ANGLICO in I Corps controlling missions which provided over 18,000 of those rounds. Again, the figures for I Corps did not include the missions fired in support of the two Marine Divisions in the corps sector. For the first half of 1968, Navy gunfire support exceeded that of the entire previous year.32
In perhaps the largest demonstration of joint supporting arms of the war, Operation Thor in July 1968, naval gunfire ships and naval air played a large role in the aerial, ground, and ship bombardment of the North Vietnamese batteries in the Cap Mui Lay sector of the DMZ. Although Provisional Corps exercised command and coordination, Navy Lieutenant Dale W. Lucas, the Prov Corps ANGLICO naval gunfire liaison officer, and his team at the Dong Ha forward headquarters, processed all naval gunfire and then passed the direction to the 3d Marine Division naval gunfire section for action. All told, for the first seven days of July, nine gunships (three cruisers and six destroyers) fired over 19,000 rounds of 5-inch, 6-inch, and 8-inch ammunition against the enemy gun positions. In addition, Navy aircraft from four carriers flew 512 sorties and dropped 812 tons of ordnance upon the NVA positions. According to aerial photography and observation, the joint bombardment created extensive damage and hampered for the time being the NVA artillery support and coastal defense ability in the Cap Mui Lay area.33"
About this time, the Navy prepared to add a powerful new arsenal to its naval gunfire capability, the recently refurbished battleship New Jersey (BB 62) with its 16-inch guns. On 16 July, I Corps and Prov Corps ANGLICO liaison teams participated in a targeting planning conference for the ship which was to arrive off the waters of Vietnam at the end of September. On 30 September, the battleship fired its first observed mission against NVA positions in the DMZ which "was spotted by an ANGLICO spotter flying in a Marine TA-4F from MAG 11 . ..." According to the ground data assessment (GDA), the New Jersey's big guns silenced l antiaircraft site, destroyed l truck and 4 bunkers, and caused 11 secondary explosions. During her first month off the coast of Vietnam, the warship steamed back and forth between I and II Corps and off the coast of the DMZ. Through the end
*The Prov Corps command did not include the 1st Marine Division Task Force X-Ray which operated in Phu Loc District and the Hai Van area of Thua Thien Province. In August 1968, Provisional Corps became XXIV Corps. For the changes in the military structure in I Corps, see Chapter 13.
**See Chapter 26 for a detailed account for Operation Thor. The Navy ships that took part in the operation were the cruisers Boston (CAG l), Providence (CLG 6), and St. Paul (CA 73); the destroyers Ben-ner (DD 807), Boyd (DD 544), Cwhrane (DDG 21), Turner Joy (DD 951), O'Bnen (DD 725), and Henry B. Wilson (DDG 7); and the carriers Bon Homms Richard (CVA 31), Constellation (CVA 64), Ticmderoga (CVA 14), and America (CVA 66).
