SUMMARY

The WSAG received a briefing on the methodology employed in preparing intelligence estimates of supply movements along the Ho Chi Minh [Page 465] Trail. In the accompanying discussion, the WSAG considered the discrepancies between CIA and DIA estimates and the problems involved in comparing data from different years and in assessing the impact of the Lam Son operation on enemy supply throughput. It was agreed to hold a second WSAG meeting to discuss these topics further.
