John Adams and others going to Philadelphia

At the very end of the first episode(Join Or Die) we see John Adams, John Hancock, Robert Payne, and a lot of other men leaving Boston for Philadelphia to take part in the First Continental Congress. British troops had been moving into the city after the Boston Tea Party on orders from King George. When the American group was leaving town they marched right past a formation of British soldiers who were marching in the opposite direction, and the Americans were verbally taunting the soldiers as they passed each other. Were the British under orders not to interfere with the colonists' movements? Were the British aware that the Americans were on their way to Philadelphia in defiance of King George's order against assembly? Or were the British just not aware of what was going on? Any history buffs out there who could provide some insight? I appreciate any info. Thanks!
