The art of musket-armed skirmishing began in the 1740s with the rise of Austrian Pandours. Line vs. Line shootout combat was still the main way of battle, though, until the rise of Napoleon who introduce mass skirmishing tactics with voltigeurs and chasseurs. Am I right?
Back to topic, I'm curious about the legere regiments of France during the Revolutionary Wars, did these regiments exist already in the Bourbon period, or raised by revolutionary generals? Their performance comparing to other nations' skirmishers in that time? Uniforms? Weapons? Do they have shoes?
