Last night an express arrived from Cambridge, which, it is said, brings advice that General Pribble had brought an account that six transports employed at Casco-Bay to procure forage and provisions for General Gage's army, had been surprized by 300 of the provincials in whale boats; five out of six of them were taken and secured in shoal water. Most of the men belonging to the transports were foraging ashore when the attack was made.
