Yup.

What do you think would send a rag-tag group of fighters running, efficient use of ammo, or a regimented wall of firepower? Wars back then were won by breaking up the army so disease and desertion can take its toll, so you want your army as regimented as possible so you’ll eventually win.

Look at the Revolutionary War, George Washington lost more battles than he won, but he knew defensive wars were won through attrition, not shooting more of your enemy. So he focused on disrupting supply lines and harassing the enemy (so more disease and attrition), not on direct confrontation. I imagine other musket-era wars were similar: if you have superior numbers, you break up the enemy armies; if you have fewer numbers, you disrupt enemy supply lines. In both cases, accuracy isn’t important, strategy is.
