Charles de Saint-Étienne de la Tour, a fur trader who had become governor of Acadia in 1631, had moved to the mouth of the St. John River in present-day Saint John, New Brunswick, where he has built a new fort.

He had been formally granted a seigniory in 1635.

M.A. MacDonald writes in Fortunes & La Tour: The Acadian Civil War (1983; Toronto: Methuen) about La Tour's possession at the mouth of this river: “[d]own this river highway came fleets of canoes, bringing the richest fur harvest in all Acadia to Charles La Tour's storehouses: three thousand moose skins a year, uncounted beaver and otter. On this tongue of land his habitation stood, yellow-roofed, log-palisaded, its cannon commanding the river and bay” (p. 183).

La Tour and Razilly had agreed to divide control of Acadia, the latter controlling the southwestern corner of Nova Scotia and the territory along the St. John River.
