舍利寺
Following the Xá Lợi Pagoda raids, the senior generals started their own plot in earnest, having only had vague plans prior to this. General Đôn, nominally a high-ranking general, but in a position without command of troops since the palace distrusted him, was sought out by Mậu, who wanted to collaborate. Mậu later accompanied the ranking general in the plot, Dương Văn Minh, on recruitment campaigns. Despite his high rank, Minh was out of favour and served as the Presidential Military Advisor, a meaningless desk job where he had no subordinates in the field and no access to soldiers. Mậu helped Minh to secure the cooperation of General Nguyễn Khánh, who commanded the II Corps that oversaw the Central Highlands of the country, and Colonel Nguyễn Văn Thiệu, who commanded the 5th Division based just outside the capital in Biên Hòa. According to Thiệu, Mậu and Minh had promised to establish a more strongly anti-communist government and to keep Diệm as a figurehead president.
