LZ Carolyn anniversary

Someone reminded me that today is the 46th anniversary of the battle at LZ Carolyn in the Republic of Vietnam,near the Cambodian border, wherein the Sky Troopers of the 2nd Bn. 8th Cav. of the 1st Cavalry Division, held back the 95th Regiment of the North Vietnam Army on May 6th, 1969. From an eyewitness to history;

In the early morning darkness of 6 May, the NVA retaliated with an intensive rocket and mortar barrage, followed by a massive 95th Regiment pincer grand assault against 2 sides of the base an hour later. LZ Carolyn’s garrison was reduced by the absence of several line companies on patrol, and the withering defensive fires of the battalion’s COMPANY C and E were unable to prevent the onrushing battalions from storming through the wire and into the LZ from both directions.

Six perimeter bunkers were overrun, one of the medium howitzers was captured, and the enemy threatened to slice through the center of the base.

The Americans counterattacked with all available personnel, the officers involved being killed at the head of their troops. Artillerymen, supply and signal personnel, and engineers fought and died as emergency infantry reserves. The US counterattacks were hurled against both enemy penetrations, but the most violent fighting occurred on the northern side, where a seesaw battle raged for possession of the 155mm howitzer position. During the course of the battle, this weapon exchanged hands 3 times in hand-to-hand fighting deceded at close range with rifles and E-tools (entrenching tools, or shovels).

Overhead, rocket-firing AH1G Cobra helicopters rolled in, ignoring heavy flak, and blasted the NVA with rockets and miniguns. Air Force AC47 SPOOKY and AC119 SHADOW aircraft, supported by fighter-bombers, were employed against the numerous enemy antiaircraft weapons ringing the perimeter.

Controlled and uncontrolled fires were raging everywhere, and it seemed that the LZ was ablaze throughout its entire length. Waves of NVA infantry charging into the southern lines were met by defending troops who took advantage of the aviation gasoline storage area. The Americans shot holes into the fuel drums and ignited the flowing rivers of gas to create a flaming barrier, which effectively blocked further enemy penetration. In the LZ’s opposite sector, a medium howitzer gun pit received 3 direct hits, which touched off a fire in its powder bunker, yet the crew calmly stood by its weapon and employed it throughout the night.

Both of the 105mm howitzer ammunition points were detonated by enemy fire at around 0330, and shrapnel from more than 600 disintegrating rounds in the 2 dumps sprayed the entire LZ for more than four hours. LZ Carolyn appeared threatened with total destruction as the thundering conflagration tossed detonating artillery projectiles to shower men and equipment with flying rounds and burning shell fragments.

The defending artillerymen and mortar crews fought in desperation, heightened by the loss of communications between most weapons and their fire direction centers (FDC). The initial enemy barrage destroyed communication from the 155mm gun sections to their FDC, forcing crews to individually engage targets on their own volition by leveling tubes full of BEE HIVE or HE charges. When telephone lines from the mortar tubes to their Fire Direction Control were severed, the direction personnel switched to a bullhorn to relay fire commands across the deafening noise of the battlefield. The battalion mortar platoon’s four tubes fired 1500 rounds, ranging from critical illumination to searing WP. In all cases, effective fire support was maintained.

Ammunition shortages quickly developed, and as on-hand mortar ammunition beside the weapons was exhausted, volunteers dashed through fire-swept open areas to retrieve more rounds from storage bunkers. The destruction of the 105mm ammunition points caused an immediate crisis in the light howitzer pits.

The cannon cockers (artillerymen) were forced to redistribute ammo by crawling from one gun section to another under a hail of enemy direct fire and spinning shrapnel from the exploding dump. The crews continued rendering direct fire, even though they were often embroiled in defending their own weapons.

One light howitzer section was caught in an enemy crossfire between a heavy machine gun and rifles, until the artillerymen managed to turn their lowered muzzle and pump BEE HIVE flechettes into the enemy. All enemy automatic weapon fire against the howitzer was instantly silenced. Cavalry counterattacks reestablished the perimeter, and the enemy force began withdrawing, breaking contact at 0600.

US casualties were about 9 KIA and about 160 wounded. The NVA’s 95th Regiment suffered hundreds of dead and hundreds more wounded. The US abandoned the firebase two weeks later after the hard fought defense.
