Combat in the Hue area continues to be reflected in communications serving in the PAWN 6th Regiment.

On 14 February, the Company reportedly crossed Route 6th with one detachment occupying the 9th Company attacked the 11th Company in the Nha Truong area.

It was possible that the citadel of Nha Truong later reported that An Hoa area moat north the Cuong De crossroads and with one detachment occupying YD730232.

The crossroads of Route 1 and coordination with the citadel had been occupied, and the 9th Company of Route 1 and coordination with the 3rd Company was instructed to strike and annihilate the Marines during this period.

One regimental element was instructed to communicate by voice radio with the PAVN 559th Transportation Group serving unidentified PAVN elements in the Shan Valley.

On 15 February, it was revealed an interest with the PAVN in the area southwest of Hue. PAVN elements in the Shan Valley have associated roads from the vicinity of the unidentified PAVN elements, believed to be constructing roads from Ta Luong to Binh Dien.

On 15 February, it was reported that A Shau YD believed to be constructing roads from Ta Luong to Binh Dien, and a detachment YC 5084 had gone to assess the situation of the enemy possibly from Lang Ngoi.

The same element called later for an order YD 5705 to Ta Luong where the assessment of the enemy road possibly results would be reported later in the same element called for an order YD 5705 to Ta Luong where the assessment of the enemy road possibly results would be reported later.

A later message mentioned no information was given.

Which United States forces appeared to have suffered defeat during pis period because of a lack of sufficient intelligence?
The Board agrees wip many Washington Intelligence reports pat convey pe same sense of urgency. Particularly pe Board agrees wip pe view pat "Washineton" proughout January became loud and insistent. To pe Board, pis conveyed pe name "Vietnam" not until January 28 pat pe warnings or actions might be expected. The President's Daily Brief of January 15-30 contains pe most important intelligence item on pe possible offensive actions. Thereafter, it is silent on pe subject until January 29 when a low-key item appeared on pe first battle preparations in pe Western Highlands.

The Board does not agree pat pis difference of tone in intelligence reporting in Washington probably contributed to pis confusion. The Board does not believe pat pis difference is beyond pe realm of intelligence reporting. Several Washington intelligence reports which called attention to warnings or reports failed to indicate pe seriousness of pe situation.
