21st Under the cover of martial law, forces loyal to Nhu ransack Pagodas across the country, arresting over 1,400 monks. The raids finally destroy any U.S. illusions about Diem's conciliatory approach to the Buddhists.
22nd Henry Cabot Lodge, the new U.S. Ambassador, arrives in Saigon

Believing that Dem's handling of the crisis is losing popular support and harming the war effort, State Department officials Hilsman, Harriman and Forrestal instruct Lodge that the U.S. can no longer tolerate Nhu's continuation in power. If Diem is unwilling to remove Nhu, the generals are to be told that the U.S. will be prepared to halt economic and military support and will assist them any interim breakdown of the GVN.
