From The Plains of Abraham by Brian Connell:
While the British delegates became increasingly distrustful of what they called the trickery, time-wasting and tergiversation of the French, their opponents were putting the delay to good effect. Probing, pinpricking and plotting with the Indians, the French were determined to nullify Britain's gains in the war.
A French officer, Celoron de Bienville (Commandant at Detroit in 1743), with a small armed party was sent to make an ostentatious display of force on the long river circuit down the Allegany and Ohio and then up the Miami and Maumee back to Detroit.
