The action of 1 March 1968 was a co-ordinated attempt by four North Vietnamese trawlers to resupply the

flares.[1][2]

Background

The United States Navy, South Vietnamese navy, and the U.S. Coast Guard, operating under the authority of the South Vietnamese government, established a blockade of South Vietnam designated Operation Market Time to prevent infiltrations of personnel, munitions and equipment by the North Vietnamese government. A twelve mile wide restricted zone existed along the entire South Vietnamese coast and ships assigned to Market Time had the authority to stop and search any vessel within the zone for contraband material and check the identity papers of any person on a detained vessel.[3][4][5]

Action

Action off Bo De River

The trawler designated in U.S. Navy records as An Xuyen Province Trawler (map reference #1) was first sighted on 28 February approximately 150 miles east southeast of

Bo De River at 0200.[1] A blocking force placed near the mouth of the river consisted of several Navy PCF's and the Coast Guard cutters Point Hudson, Point Grace, and Point Marone.[7] Winona fired warning shots eight miles off the coast which were ignored so she opened up with her 5-inch/38 caliber gun after receiving return fire from the trawler.[8][9] The trawler exploded in a huge fireball after taking several direct hits and sank approximately seven miles off the beach.[1][10] Winona was struck by several pieces of debris from the explosion, however only minor injuries were sustained by the crew during the action.[11]

Action off Nha Trang

The trawler designated Khánh Hòa Province Trawler (map reference #2) was first sighted by Market Time aircraft on 29 February approximately 90 miles east northeast of

AC-47 gunship, swift boats PCF-42, PCF-43, PCF-46, PCF-47, PCF-48 and two SVN junks sortied to help the patrol craft chase the trawler to a cove where it ran aground in the Hon Heo Secret Zone[1][10][13] At 0230, 1 March, five 81-millimeter mortar rounds from PCF-47 were direct hits and the trawler exploded with a massive explosion due to the munitions aboard.[1] Fourteen dead North Vietnamese sailors were recovered the following morning. Rifles, machine guns and rocket launchers; along with considerable ammunition and explosives were recovered from the sunken trawler. The salvage operations extended over 12 days and included the recovery of a 14.5 millimeter antiaircraft gun and 68 cases of ammunition.[1]

Action off Tha Cau River

Forty miles from Chu Lai and six miles off the coast, (map reference #3) USCGC Androscoggin intercepted a third trawler designated in U.S. Navy records as the Quảng Ngãi Province Trawler. Androscoggin signaled the trawler to identify itself at 0112 but there was no response so Androscoggin shot 5-inch star shells into the air to illuminate the trawler.[14] It was then that the trawler was positively identified as an SL class North Vietnamese trawler so the Androscoggin opened fire at 0120 with 5-inch high explosive naval gunfire and .50 caliber machine guns.[15] The trawler returned fire with a recoilless rifle, laid a smoke screen and turned into Androscoggin's direction but one of the cutter's shells hit the after starboard side, so the trawler turned reversed course and headed for the shore.[15][16] As a result of a civilian junk passing through the battle area the Market Time ships had to cease fire.[17] Two United States Army helicopters were directed to engage the trawler with rockets and miniguns at 0129 and after their attack a reduction in the amount of fire coming from the trawler was noticed.[15] At 0140 Point Grey, Point Welcome, PCF-18 and PCF-20 were ordered to take the trawler under fire with mortars and machine guns at close range because the trawler had moved too close to shore for Androscoggin to maneuver.[17][18] Point Welcome struck the trawler twice with 81-millimeter rounds.[15] The trawler then grounded 50 yards off the mouth of the Tha Cau River at 0210.[15] At 0220, the North Vietnamese tried to scuttle their ship and failed but a second attempt at 0235 succeeded in destroying the vessel in a 500-foot fireball.[19] The explosion caused some damage to the pilothouse of Point Welcome and the deck was littered with debris but no casualties were reported.[15]

Other action on 1 March

People's Republic of China.[1]

While on Market Time patrol duties on 1 March, USS Persistent discovered an abandoned junk at anchor 52 miles southeast of Da Nang. After a search of the area failed to locate persons in the water, the junk was boarded and items were found of a Communist Chinese origin including a Communist Chinese flag. The junk was hoisted on board Persistent and delivered to Da Nang for further inspection.[1]

Aftermath

The destruction of three of the four trawlers and the turning back of the fourth demonstrated that Operation Market Time was an effective net for the interception of supplies destined for resupply of the Viet Cong. Except for the 1 March trawlers and one other instance in the days after Tet 1968 no other trawlers were spotted between July 1967 and August 1969.[21] The North Vietnamese were forced to use the Ho Chi Minh trail through Laos or the neutral port of Sihanoukville in Cambodia to ship supplies to the Viet Cong. With the closing of the port at Sihanoukville to Communist shipping in August 1969, attempted North Vietnamese trawler traffic into South Vietnam resumed.[Note 1][22] Of 15 trawlers detected by Market Time assets from August 1969 to late 1970, one was sunk, 13 were turned back and only one got through.[21] In 1970, ten out of eleven trawlers were either sunk or were turned back.[21]
