A slower firing matchlock (not really that much slower) benefit even more from having a bayonet as backup.
First sailing ship rams and now this...
For those who might be interested, here's a nice little firearms
blog entry discussing matchlocks, firing procedures, and other actual facts. There's even a video for the
Too Long, Didn't Read crowd.
Matchlock firing drills involved two dozen steps or more as the musketeers loaded and primed their weapons while also juggling a lit length of slow match so they didn't also touch off the gunpowder they carried by accident. A soldier carrying a flintlock on the other hand could reload in under ten steps because he didn't have to worry about a mishandled match setting off his ammunition supply. Flintlocks could also carry more ammo because they didn't need to keep their immediate reloads in little wooden bottles.
The blogger states he thinks he could load as fast as 15-20 seconds, but that a minute would be much safer especially in battle.
I'll also point out the undeniable balance issues with the matchlock and the use of the musket rest. When you read the blog, you'll understand that the rest was first used because the matchlock was heavy but quickly evolved a more important role as a slow match holder.
The lit slow match is the musketeers' most dangerous piece of equipment, so the musket rest was quickly used as a holder for it so the musketeer could use both hands to load and prime the weapon. Once the gun was ready, the musketeer would place in on the rest, attach the slow match to the serpentine, and touch the piece off.
When the matchlock finally became light enough, the rest was done away with but the flintlock and other weapons were already in development by then.
Could the bayonet have been developed earlier? Sure. Was there a pressing need for it? No.
Necessity is the mother of invention and no one saw the necessity as quickly as we would have liked them to.
