In New England at least, the "militia regulations" of the late 1700s were actually quite rigorous. These laid out and specified in some detail not only the musket, but also the cartridge box, and the edged weapons required. This was at a time, recall, where the term was a "stand of arms." A "stand" implied not just the fowler or musket, but also the bayonet and cartridge box and cross belts and even a few simple tools to service the firelock. In deference to the civilian fowler pressed into militia service, a sword, hanger, cuttoe, or hatchet/ tomahawk could be substituted. "Minute men" had to have a powder horn or even cartridges ready to go in the household.
In Spanish America, the regulations for the Presidio soldiers called for six pounds of powder per man per annum. But in fact, many soldiers had to make do with just three! This meant that there was little if any opportunity to fire practice rounds, and what little they had was carefully husbanded. Small wonder that the espada ancha/ short sword/ hanger was almost always carried--or indeed the Model 1728 broadsword--which is a big sword!--and the lance remained a primary weapon on foot or on horseback long into the 19th century. It didn't have to be reloaded, it was cheap, reliable, robust, easily repaired, and quite deadly in practiced hands. In the case of San Antonio de Béxar, powder was stored in a polvorín or magazine outside the vulnerable city limits under guard. Woe betide anyone who set off rockets or fireworks near the place... Penalties for doing so specified many "azotes" or blows in the public flogging that would ensue.
By the time of the Napoleonic Wars, cartridges were made in vast numbers and even began to be distributed in packets of ten to fifteen, with a gun flint for every twenty cartridges issued.
