    During the early summer months of 1966, evidence was mounting that large NVA forces were building up in Northern Quang Tri Province, Vietnam.  With rare exception, most recon inserts were encountering armed, uniforned NVA  throughout the province.  Deserters stated the NVA were there to drive the ARVN  out of the province.

    General Walt (CG III MAF) met With General Westmoreland in Hue and discussed Operation HASTING.  Westmoreland approved and authorized Walt to transfer up to an entire division to the Quang Tri Province.

    Gen Kyle (CG 3RD MARDIV) established the 4th Marines (forward) at Dong Ha, and activated Task Force Delta headed by his Asst Div Cmdr, Gen English, in preparation for the operation.  The Task Force included four infantry battalions (2/1, 1/3, 2/4, and 3 / 4).  3/12 Artillery Battalion  also joins the task force.

    Based on intelligence reports, General English decided to seek the NVA in the Song Ngan Valley.


    Deckhouse II began with an amphibious assault conducted by BLT 3/5 in an area just north of the Qua Viet River near Dong Ha,  in Quang Tri Province.  The purpose of the assault was to support 3d Marine Division in Operation Hastings-the largest Marine operation in Vietnam at that time.  BLT 3/5 mission along “The Street without Joy” was to halt NVA movement across the DMZ and to root out enemy units already inside South Vietnam.  Plans call for BLT 3/5 to assume blocking positions about eight miles north of Dong Ha after landing via a combination of surface and helicopterborne lifts.  In accordance with amphibious doctrine, once the landing force was firmly established on shore, Deckhouse II would be terminated and BLT 3/5 would conduct further operations inland under the  OPCON of Task Force Delta of 3rd Marine Division.

    BLT 3/5 was airlifted into the area to exploit the B-52 strike and act as a blocking force for any NVA units escaping from the Song Ngan area where most of the Task Force were located.  No friendly forces had operated in BLT 3/5 initial zone of action prior to their entry.  It was suspected that the area might include a regimental sized CP, and perhaps, even the CP for the 324B NVA Division.

    BLT 3/5 was commanded by LtCol Ed Bronars, with his able commanders, Capt Hans Haupt (H&S), Capt Sam Glaize (I Co), Capt Dick Maresco (K Co), Capt Reiss Tatum (L Co), and Capt. Harold (Dell) Pettengill(M Co).

    In the initial landing, only Capt. Pettengills M Co. encountered serious resistance.  The company landed on an NVA unit in LZ CROW  at 043623. and after heavy airstrikes were able to overrun the NVA. 20 NVA killed during the afternoon battle.

    L Co also landed in LZ CROW.  Cos K, I, H&S, and BLT CP landed in LZ DOVE.
