How are Paul Revere and Johnny Tremain the same and different?

Paul Revere is a silversmith and a rebel who offers to buy Johnny’s spare time from Mr. Lapham. He is known for his exceptional metalworking skill and has started a prosperous business. He eventually becomes a spymaster for the rebel movement and fights bravely in the Revolution.Johnny too is skilled at silverwork and has a great desire to be part of the rebel movement. Unlike Paul, Johnny does not actually fight (because of his hand) but contributes to the rebels in other ways.
