Gun recovered in 1973 from the St. Lawrence River off Fort Haldimand, Carlton
Island, Cape Vincent, NY
The gun is
a 9Pdr of 9 Ft 6 Ins (guns are recorded to their nearest 6 Ins). It was cast
between 1731 and 1748. Probably in the period 1731 - 1734. 9pdrs for garrison service (usually
long guns) were sent out to New England, including Boston, in 1754. On 19th May
1757 Govenor Shirley took some guns, including 2 X 9drs, out of Boston for
service at Oswago and Crown Point. None of these guns were returned. More guns
were taken later by Abercromby but these would seem to have been the 18Pdrs of which
two burst in the defense of Fort William Henry.
