to fight the invading British Army ????
Most of america was an English colony. The French were causing mischief in the south and north east, slaughtering the local inhabitants as though they were pests, which made the local inhabitants dislike all europeans.
The Dutch and English settlers begged the English to send troops to defend them, which England did, at England's expense. The few English troops routed the French, parleyed with the local inhabitants and would have withdrawn.
Sadly, before all were withdrawn, some of the settlers were beastly to the local inhabitants, at which point the English decided that the settlers should help finance the remaining troops, which they agreed to do; however, when the English realised that the local inhabitants were not the trouble makers and tried to be even handed, the settlers, unjustifyably, felt agrieved.
The result was that they rebelled against the troops that they had asked to help, so that they could take on from the way the French had behaved, slaughtering the local inhabitants and stealing their land, and to do this they gave themselves the "right" to form raiding parties and carry guns.
Please don't start a flame war because your history books are inaccurate !
Apologies Bettypooh.
