YORK, PENNSYLVANIA—Volunteers assisting with the investigation of Camp Security, where more than 1,000 British troops who surrendered at the battles of Saratoga and Yorktown were held, found eighteenth century buttons, a British half-penny adorned with a bust of King George II, and a lead musket ball. One of the buttons was made of tombac, and alloy of zinc and copper. Another button, made of brass with a star-like design, was common during the Revolutionary War period. “Now we don’t know what part of the site we’re on at this point in time. We won’t know that until we’ve done a lot of testing. So we’re hoping to gather that information over the course of the next several weeks,” archaeologist Steve Warfel told The Evening Sun.
