The regiment left their camp near Big Bethel and marched to Howard's Bridge. After turning off the main road, the regiment heard musket fire as they passed near a Confederate camp which had recently been vacated. The regiment moved into a clearing where they made their camp, nearly four miles from Big Bethel and five miles from Yorktown. The Confederates were camped in a large semicircle nearly a mile from the Union line in the vicinity of Wynn's Mill works.1
