These were (roughly), the XVIII Airborne Corps troops, the Maryland National Guard, and troops from the 197th Infantry Brigade from Fort Benning, Georgia (which arrived two days later). The 1,300 troops of the Maryland Air National Guard were organized in a provisional battalion and used to guard critical infrastructure throughout the city, as well as an ad hoc detention facility at the Baltimore Civic Center. Task Force Baltimore peaked at 11,570 Army and National Guard troops on April 9, of which all but about 500 were committed to riot control duties. Unrest continued for several days as the Task Force sought to reassert control. Early on April 12, federal troops began to depart and by 6 pm that evening responsibility for riot control returned to the National Guard. At midnight Task Force Baltimore ceased to exist and the remainder of federal troops were withdrawn. Maryland National Guard troops remained on duty in the city until April 14, when Agnew declared the emergency over and sent them home. After action reports credited both the National Guard and active Army forces for being extremely disciplined and restrained in dealing with the disturbance, with only four shots fired by National Guard troops and two by active Army troops. These forces had received orders to avoid firing their weapons, as part of an intentional strategy to decrease fatalities. A total of 10,956 troops had been deployed.
