The majority of the Spanish troops came from Louisiana with some aid from Cuba with a few regular units. The primary regular unit was the two battalion Louisiana regiment. Militia forces were divided into white, black and mulattoe companies with the quality of units varying greatly. The black companies seem to have had the most active duty/experience due to their frequent employment to hunt down runaway slaves. Spanish militia companies were almost all uniformed. Even those on the frontier, such as in the St Louis area, had uniforms. The condition and quantity (enough for everyone) of the uniforms is speculative.

The St Louis garrison during 1780 consisted of FIVE companies. The two regular companies of the Louisiana Regiment averaged between 50 and 60 men and were posted in small garrisons at various posts along the Mississippi River. A Mounted Militia unit consisted of 54 men. Two foot militia companies averaged 90 men each. These militia units were uniformed but also included local trappers and settlers in Frontier dress.

The 1780 New Orleans mobilized garrison included Louisiana Regular Regiment (fixed) consisting two battalions. The First battalion contained 8 companies of Fusiliers plus the Dragons of America (Louisiana). The Second battalion contained 8 Fusilier companies plus 2 Grenadier companies. Each foot company averaged 60-70 men. Some of the militia and volunteer units included the Louisiana Rangers (3 companies one White , one negro and one mulatoe/Pardos), Louisiana Grenadiers (3 companies one White , one negro and one mulatoe/Pardos), Cataluna Volunteers, New Orleans Carbineers, New Orleans Free Pardos and Negroe Militia, Louisiana Militia of Armed Negoe Slaves and one artillery company.

After the war several militia and volunteer units were increased in size and some kept on a fixed/ full time status. The Negro and Pardos companies in particular were used to garrison various small posts, search for runaway slaves and quell any rebellions. These companies also comprised part of the garrisons at Pensacola, Mobile and St Augustine. By 1793 the Miltia had been reorganized into a two battalion regiment with each battalion consisting of 4 Fusilier companies and a grenadier company.

I also found notations for a unit called the Royal Mounted Legion of Mississippi. It was supposed to have consisted of 4 Squadrons of Dragoons (each of 150 men) and two foot battalions of 5 companies each (135 per company). This would have given a strength of 617 Dragoons and 1350 infantry. . It may have been the name for the post-war militia force. Still because of the what-if situations and possible actions against Native Nations, I have listed its uniform in the charts below. By 1792 the New Orleans Carbineers had been increased to two companies of 40 men each.

As with most amphibious/ naval operations a number of men were formed in ad hoc units to fight on land. Their main task being to man artillery guns, some being brought from the ships, and to provide protection for the batteries. At Pensacola these men formed the Fourth Brigade. Another group of Spanish sailors were merged with French sailors to form the Corps of Artillery.

According to Dr Thomas Chavez (Palace of Governors Museum, new Mexico), the following Spanish regular Regiments were employed in operations in North America and the Caribbean during the American Revolution. Along with the units are their unit strengths for the Battles of Mobile and Pensacola. N/A indicates that the unit was not present. Some numbers are estimates but are based on the sources listed in the bibliography. The reports on the Spanish units at Mobile refer to the same unit as the 2nd Bn Espana and also as the Principe.

At Mobile 323 White Militiamen are reported but are not divided by unit. I divided them among the White units which fought at Pensacola, except the Havana Fusiliers, and the numbers balanced. American patriots were represented at Mobile by 26 volunteers from New Orleans. The units are:
