Note 124 — Chapter XIII
Reading edition
The reader will do well to consult Belknap's admirable "History of New Hampshire," vol. ii.; Adams's "Annals," or Brewster's "Rambles about Portsmouth." Some sort of defense was begun here very early. In 1665 the commissioners of Charles II. attempted to fortify, but were met by a prohibition from Massachusetts. In 1700 there existed on Great Island a fort mounting thirty guns, pronounced by Earl Bellomont incapable of defending the river. Colonel Romer made the plan of a new work, and recommended a strong tower on the point of Fryer's (Gerrish's) Island, with batteries on Wood and Clark's islands. In December, 1774, John Langdon and John Sullivan committed open rebellion by leading a party to seize the powder here. The fort was then called William and Mary. Old Fort Constitution has the date of 1808 on the key-stone of the arch of the gate-way. Its walls were carried to a certain height with rough stone topped with brick. It was a parallelogram, and mounted barbette guns only. The present work is of granite, inclosing the old walls. The new earth-works on Jaffrey's Point and Gerrish's Island render it of little importance.
