In each infantry and cavalry regiment there were ten companies.[127] The original strength of each company was from 64 to 100. Later the number was fixed at 104 to the company for infantry, 72 for cavalry, and 70 in the artillery. After the formation of new commands had practically ceased, the number for each company of infantry was raised to 125 men, 150 in the artillery, and 80 in the cavalry.[128] The original strength of each infantry regiment was, therefore, from 640 to 1000, not including officers; of cavalry, 600 to 720. A battery of artillery seems to have had any number from 70 to 150, though usually the smaller number. The size of the regiments varied greatly. Colonel Fowler reported that to February 1, 1865, 27,022 men had joined the 20 Alabama regiments in Virginia, an average of 1351 men to the regiment. Brewer gives the total enrolment of 15 regiments in the Army of Northern Virginia as 21,694, an average of 1446 to the regiment.[129] Four of these regiments had an enrolment of less than 1200;[130] so it is evident that the other 5, not given by Brewer, must have averaged about 1265 to the regiment.[131] These numbers include transfers, details, and reënlistments, the exact number of which it is impossible to ascertain. Brewer lists the transfers and discharges from 15 regiments at 4398, an average of 293 each, of which about one-third seem to have been transfers.[132] There were also many reënlistments from disbanded organizations.[133] Both Brewer and Fowler count each enlistment as a different man and arrive at about the same results.[134] The enrolment of 8 Alabama regiments in Johnston's army, as given by Brewer, amounted to 8300, an average to the regiment of 1037.[135] It was the practice, in 1864 and 1865, to unite two or more weaker regiments into one. No Alabama regiments in Virginia were so united, and of the 8 in the Western Army, whose enrolment is given by Brewer, only 1 was afterward united with another.[136] It would then seem that the enrolment of the strongest regiments is known.[137] The total number of enlistments in the Alabama commands in Virginia was, according to Fowler, about 30,000, and these were in 20 infantry regiments, and a few smaller commands. In the armies surrendered by Johnston and Taylor there were 38 Alabama infantry regiments, and 13 of these had been consolidated on account of their small numbers. Eight of them which remained separate and which must have been stronger than the ones united had enrolled an average of 1037 (according to Brewer). Thirty-eight regiments of this strength (which is probably too large an estimate) would give a total enrolment of 39,406. This number, added to Fowler's estimate of 27,022 in the Army of Northern Virginia, will give 66,428 enlistments of all kinds, for the infantry arm of the service. Add to this 3000 for the 3 regiments of reserves called out in 1864,[138] and the total is 69,428 enlistments in the infantry.
