This Memo, from Robert N. Ginsburgh, on behalf of Walt W. Rostow, to the President, confirms the following points on North Vietnamese infiltration into South Vietnam: 1) infiltration is continuing at the same high level of the first four months; 2) the enemy can probably continue current intense levels of activity--assuming current rates of attrition; 3) 2 out of 5 infiltrators are headed for Saigon; and, 4) on basis of in-house calculations, monthly infiltration may be as high as 18.000 instead of General Westmoreland's end-April estimate of 12,000.
