The last major weapon system purchased by the Army was 4 field guns for the Field Artillery Battery. The guns, carriages, limbers, caissons, and battery wagons cost a handy sum of $979, the most expensive weapon to date for the Army.
Taking note of the Texas Navy's favorable reports on the British Armstrong guns, the Texas Army selected 12 pounder rifled breech loaders. These field guns moved between the frontier and the border, augmenting the cavalry and infantry where they were needed.
Struck by the same budget constraints as the Navy, the Army suffered no reduction in forces but plans for a second infantry regiment and field artillery battery were postponed.
