Boston’s division of the force, thereafter to be known as the Massachusetts Volunteer Militia, paraded in two brigades, with a total strength of 2,500 men. Incidentally we might note that there were two other such divisions in the state. Under the circumstances the 1st and 2d Battalions of Artillery added to their already creditable reputation and presented a fine appearance. There were five companies in the two battalions, each consisting of a captain, two lieutenants, four sergeants, four corporals, six gunners, six bombardiers, one drummer, one fifer, and sixty-four privates or “matrosses.” Part of each company was armed, equipped and drilled as infantry; but each company proudly exhibited two bronze six-pounder cannon with limbers, and a single caisson. The ordnance had increased in caliber since 1784, the change being made in 1840. The state prescribed by law what manner of uniform the artillery companies should wear. Inasmuch however as the members had to purchase their own clothing without state assistance, and since they were mostly interested in the glory of their own companies, they were pardonable for regarding the regulation state uniform as merely a point of departure from which fancy might soar in devising distinctive costumes for the company units. Caps, short jackets, and frock coats, soon to become popularized as a result of the Mexican War, were beginning to be in vogue. The year 1844 marked a still more important step in the development of the artillery battalions. Train-band companies of each district had always been organized into regiments, and the regiment was conceded to be the fundamental unit in importance. It was the tactical unit, that is, the troops maneuvered as regiments when in the presence of an enemy. It was also the administrative unit, in the sense that all records and reports centered at regimental headquarters. In drill regulations, the regiment was called a battalion; but no battalion could claim to be a regiment unless it had approximately ten companies, and was commanded by a colonel; one thousand was the membership standard. In other words the regiment was the only complete battalion. When the train-band ceased to be, the battalions of artillery began to aspire after regimental dignity in the Volunteer Militia. The 1st Battalion had actually been a regiment for a few months, ten years previously. Nor was it forgotten that the two battalions were originally one, that the regimental consolidation to be was really a reunion of those who, forty-six years before, had been a single body. On June 4, 1844, their wish was gratified; and the 5th Regiment of Artillery came into being. With the promotion on June 24 of Andrew Chase, Jr., to the colonelcy the new organization was completed.
