Chapter 1. Organization and Arms, 1836-1839
A division of 36,000 men doesn't have any strength unless it is organized properly. One of the problems that befell Poinsett was how to organize this massive unit (no other army had divisions of this size) in such a way as to allow it freedom and flexibility for movement, but also to maintain unit cohesion in the face of large-scale opposition. To this end, the Big Red One was composed of three brigades, each with a full strength of 12,000 men, or about the size of the largest divisions in other armies. This large size was designed the unit to be able to operate on it's own against multiple foreign (presumably European) divisions. These three brigades, numbered I, II, and III, each consisted of six regiments of 2,000 men. This, however, is where the division's order of battle began to get complicated.
In I and II Brigades, each regiment was uniform. They consisted of three battalions, each with a combat strength of 650. The remaining 50 soldiers made up the regimental Headquarters platoon. Each battalion had four infantry companies with 130 men, and an attached long platoon of 50 cavalrymen. The final 80 men in each battalion were charged with manning and defending the battalion artillery. Each battalion’s attached artillery consisted of a battery of four 9-pounder muzzle-loading cannon (Figure 1). This artillery gave the infantry support that would be close to their positions in the lines, and easily able to support any offensive or defensive moves they might make.
In the infantry companies, the 130 men were divided into four platoons; the first and third platoons had 33 men, the second and fourth platoons had 32. These platoons were further divided into sections of 11 (the shorter platoons had 1 section of 10). The long platoon of cavalry was divided up into two squadrons of 25. The artillery “company” was likewise broken up into smaller units, 4 ‘guns’ each of 20 men, and obviously, 1 cannon. Besides the actual gun crews, the ‘guns’ included drivers for the limber and caissons, all of whom would be expected to fight if the need arose.
By contrast, III Brigade was different. Five of the brigade’s six regiments were identical to those found in the other units, but the sixth regiment was the divisional artillery arm. There was a headquarters platoon, consisting of 50 men, just like those from the other 17 regiments, and the men themselves were divided into three battalions. Besides an additional long platoon of 50 cavalry, each battalion of artillery had 5 companies of 120, as with the infantry battalions. Each company was essentially a battery of 6 guns, mostly the same 9-pounders, but some were heavier 16-pounders, and there were even a few colossal 36-pounders. The artillery companies themselves were organized the same way as the ones in the infantry battalions, but on a larger scale.
The weapons used by the division were several-fold. The infantry’s standard arm was the newly-designed issued Springfield Model 1838 (Figure 2). This was a modern percussion rifle, using the French-designed Minie ball. A .54 calibre weapon, it was of a smaller bore than the .69 calibre flintlock muskets that had been used previously, but, though it remained a muzzle-loading rifle, its rate of fire was double that of a flintlock (between 4 and 8 rounds per minute), and it was accurate out to a much longer range (between 600 and 800 yards). The cavalry were armed with Model 1837 Colt Revolvers (Figure 3) and Model 1836 Hall Carbines (Figure 4), and sabers (Figure 5), although these were mostly ceremonial. The revolvers and carbines were both rifled, breech-loading weapons, and together, they gave the cavalry arm a large amount of firepower. The Hall, while still a rifled weapon, was not nearly as accurate as the Springfield, and even with its fast rate of fire, was not suitable for infantry combat.
