What uniforms did Mexican Presidio soldiers wear in the 1800s?

Mexican soldiers wore uniforms of dark blue wool jackets with scarlet collars and cuffs and brass buttons, matching wool trousers, and wide-brimmed black hats. But for protection from indigenous peoples’ arrows, the soldiers wore leather coats that hung to their knees. They carried long lances and leather shields as shown in this photograph. This display is in the San Francisco Presidio museum on the site of the original Spanish Presidio. Because the soldiers often herded cattle and horses, rode as escorts for the friars, and carried mail between presidios, the cumbersome leather coats were shortened to jacket length. The jackets were made of antelope hide with red felt collars and cuffs. Antelope-hide leggings or breeches covered the soldiers’ legs.
