In 1762, Bethlehem built the first water-works in America to pump water for public use. Bethlehem and the surrounding area saw a large influx of fleeing Patriots as the British advanced upon Philadelphia in the autumn of 1777. The Marquis de Lafayette recovered from an injury received at the Battle of Brandywine in Bethlehem and several members of the Continental Congress fled north to Bethlehem before the congress eventually reconvened in Lancaster. While George Washington and his troops stayed in Valley Forge, Washington stored his personal effects at the farm of James Burnside in Bethlehem – a historical museum (James Burnside Plantation).
