Drumbeats in Williamsburg by Isabelle Lawrence is the sequel to A Spy in Williamsburg. Several years have passed for the Budge family. The American Revolution has been going on for many years, both William and Ben Budge are away with the American army. At home, the Budge women are doing whatever they can to provide for themselves and make ends meet while the men are away. Then one day, their cousin Andy arrives from Philadelphia sent by his mother in an attempt to keep him safe. Andy, who wants more than anything in the world to be a drummer boy in the American army, is at first disappointed to be sent away; however, he soon finds that Williamsburg is far more exciting than Philadelphia. He meets General LaFayette, rescues a runaway British drummer boy, impersonates him to spy on the British, and finally becomes a drummer boy just in time for the final battle of Yorktown.
This is also an older book and currently out of print, but it is definitely an nice read for ages 10 and up or a read aloud for younger kids. It does an excellent job of giving the reader an in depth look at the events in Virginia leading up to the battle of Yorktown.
