In the failed attack on The Capitol they definitely came by land…
One if by Land, and Two if by Sea
There were two routes that the British soldiers could take: by land through the Boston Neck and by sea across the Charles River. Paul Revere arranged to have a signal lit in the Old North Church – one lantern if the British were coming by land and two lanterns if they were coming by sea – and began to make preparations for his ride to alert the local militias and citizens about the impending attack.
