Active measures were at once instituted to clothe, arm with Enfield rifles, and equip these companies, to be in readiness for a quick departure. Complete uniforms, with equipments, were issued at Readville. Many companies went into camp several days previous to July 18th, gaining recruits every day until ready for muster in for service. Captain Scott failed to recruit more than thirty men. Captain Prouty failed to recruit his company, although at one time it promised well; from some cause his men scattered to other companies or went home. Companies commanded by Captains French and Stewart, already mustered into service, were assigned to the regiment as Companies A and H.
The first regimental morning report was made up July 20th, and showed a strength of thirty-five officers, seven hundred and thirty-eight enlisted men, present and absent. The regiment was ready for marching orders July 23d, with the following strength:
