Archaeologists have uncovered artifacts from a site in northern New Jersey where American soldiers may have camped early in the Revolutionary War.

A survey conducted last week on an unspoiled swath of land about 15 miles west of Newark Liberty International Airport produced several dozen items. These included metal buckles, a knob from a desk drawer and the bowl of a pipe.

American history author William Styple (STEYE'-puhl) believes those artifacts are proof that Gen. George Washington's army made camp there for several months in the winter of 1777. That was a year before the ragtag group wintered at its more well-known refuge at Valley Forge, Pennsylvania.

If he's right, it could add a chapter to the historical record of the Revolutionary War that's been hinted at but never fully explored.
