Come on! You are in no position to invade England. You have popular support but are too poorly equipped to take on Edward I's well-armed forces. Even if you made it through the border, you would come face to face with a force of mounted knights and skilled archers – Edward's army is not to be reckoned with.
Bribe some of the English officials into joining your cause. You need some support and this option will give you some momentum.
Attack the many stone garrisons and fortresses of the English army up and down the land. You need to show them what the Scots are made of.
