Over the next several years settlers continued to encroach on Wabanaki lands east of the Kennebec River, including the construction of block house fortifications on the east side of the Kennebec River. The Wabanakis responded by raiding livestock. Canso, Nova Scotia, a settlement disputed by all three parties but fortified by Nova Scotia and primarily occupied by Massachusetts fishermen, was also a flashpoint for conflict. After receiving complaints of harassment and raids from Canso-based fishermen in 1718, Shute dispatched a Royal Navy frigate to the area, which seized French ships and goods. Tensions there were further raised when Canso was attacked in 1720 by the Mi'kmaq.
