This question is in relation to infantry who carried swords as their primary weapon during the 1600s (so I'm discounting musketeers or pikemen armed with backup short-swords). I've come across the Rondartschiere, but don't know anything about them other than they were guys armed with swords (of some make) and round shields (hence the name). Could anyone elaborate a bit more on who those guys were, and whether there were any other units/types of European infantry during the 1600s that carried swords as their primary weapon? I know that in the 1500s some of the Landsknechte carried two-handers, but I don't know if that practice lasted on any scale into the 1600s. I'm also somewhat familiar with the Spanish Rodeleros from the 1500s, but again I don't know if they lasted into the next century.
