Prior to the Act of April 16, 1862, the Confederate government had no plan or organization for military recruiting. This came much later when the Conscript Bureau came into being. In December 1861 Congress passed the Furlough and Bounty Act, designed to encourage more volunteers to enter the army. It effectively disorganized many veteran organization enrolled under a twelve-month term.

As for the large number of men enrolled in March 1862, it will help to understand what was happening during that time. The capture of Forts Henry and Donelson in February created an urgent need to replace the regiments captured and support the badly outnumbered Confederates retreating south through Tennessee. The War Department sent an appeal to governors of the Deep South states to ask for more troops as quickly as possible. In turn governors issued public appeals for volunteers.

Governor John Gill Shorter of Alabama issued a call for twelve new regiments of volunteer infantry. Newspapers carried this appeal with the implied threat that if a sufficient number of volunteers did not come forward, state authorities would take steps to make up the deficit by draft in each county and beat. The Governor also called for regiments of ninety-day volunteers to take the place of veteran commands in coastal defenses.

In Alabama a large number of men came into service under the Governor's proclaimation and supplemented by the later Conscript law. New regiments included the 30th, 31st, 32nd, 33rd, 34th, 35th, 36th, 37th, 38th, 39th, 40th, 41st, 42nd, 43rd, 44th, 45th, 46th, 47th and 48th, plus the 2nd Alabama Cavalry Regiment and several artillery batteries. Four 90-day regiments enlisted, but most officers and men were discharged after the Conscript Act went into effect.

March 10th fell on a Monday. I could be that the initial call for volunteers required a cerain number to come forward and volunteer for the war within 'x' number of days after the public call for volunteers was issued. In any case, it had nothing to do with recruiting officers visiting towns. The only event like that would have been an officer of the PACS being called to a place of enrollment to formally muster troops and sign the original roll that went to the War Department.

Don't know specifics about Georgia, but Governor Brown must have acted in similar fashion.
