Just my two cents. I think we are coming from very different views of our character's life experience, knowledge and abilities. I believe that we are at the extreme low end of the life spectrum. Young, inexperienced and unskilled. I try to look back at where I was when I was 19-20 years old and even if I were a budding hero, who in their right mind would follow me? Plus, I don't think we have the martial skills yet to put up any serious resistance. Any moderately skilled knight would wipe the floor with a bunch of unarmored newbies.
I think our primary goal is going to be to hone our skills, build our reputations and just stay alive. We have no food, little equipment and no money. We need to establish a hidden base of operations with a ready supply of butter and guns. Eventually, as we gain more skill and experience, I expect we would begin harrying actions against their supply lines. Ambushes. Isolating small groups of "bad guys" and overwhelming them. I think if are good at a guerrilla war, then people will be drawn to us.
But right now, I don't even begin to know how to turn a ragtag band of scattered, surviving peasants into an army.
I'm no history expert, but I was watching the History Channel this weekend and they had a profile of the Celtic queen Boudica. She led a peasant uprising that eventually challenged the Roman empire in Britain. HOWEVER in her final battle, 250,000 or so Celts were massacred by 10,000 Roman legionaries. A small group of skilled, heavily armored and armed opponents destroyed a bunch of peasants. The Celts lost more than 80,000, the Romans 400.
So, I think any direct action against the main body of the attackers right now would be suicidal. An attack on a roomful of 30 armored knights would have been a massacre -- of us. A handful of knights without shields and a bunch of squires gave us a run for our money.
