Young sapwood in a sample of oak, the thick outer section of the tree where sap flows is an indication that this tree was likely felled during the last ring shown on the sample, which cross-dates to 1773, though the outer layer of bark is missing and the rings are extremely tight and difficult to count making it also possible that the tree was cut down in 1774 or 1775.

The keel was squared-off during its construction, making the last ring in the shargbark hickory sample which cross-dates to 1724 likely a ring closer to the heartwood of the tree. (Courtesy Neil Pederson, LDEO Tree Ring Lab)

Oil painting of by V. Zveg in 1973, depicting Continental Sailors and Marines landing on New Providence Island, Bahamas, on 3 March 1776. Their initial objective, Fort Montagu, is in the left distance. Close off shore are the small vessels used to transport the landing force to the vicinity of the beach. They are (from left to right): two captured sloops, schooner Wasp and sloop Providence. The other ships of the American squadron are visible in the distance. The operation was commanded by Commodore Esek Hopkins. (Courtesy of the U.S. Naval Historical Center.)
