Meanwhile, the chairman of the Free Officers, Gamal Abdel Nasser, contacted the Muslim Brotherhood and the Communist Democratic Movement for National Liberation to assure their support. On the morning of 23 July, he and Abdel Hakim Amer left Mohieddin's home in civilian clothes and drove around Cairo in Nasser's automobile to collect men to arrest key royalist commanders before they reached their barracks and gain control over their soldiers. As they approached the el-Qoba Bridge, an artillery unit led by Youssef Seddik met with them before he led his battalion to take control the Military General Headquarters to arrest the royalist army chief of staff, Hussein Sirri Amer and all the other commanders who were present in the building. At 6:00 am the Free Officers Air Force units began circling Cairo's skies.
