[10] On December 25, 1776, Jehu Eyre "had charge of the boats" in Washington's crossing of the Delaware,[11] a resounding success and a critical battle that saved the Revolution from being snuffed out in its infancy.
Following the British occupation of the city in 1777, the naval works at Kensington were destroyed, to be rebuilt after the conflict's conclusion by Jehu's children and grandchildren.
[15] One of the frigates built by the Eyres, The Alliance, carried the Marquis de Lafayette to France in 1779 and then joined up with the fleet of John Paul Jones.
