On the third of June, Christie, then safely ensconced in the fort which he commanded, had written as follows to his superior officer, Lieutenant Gordon, at Venango: “This morning Lieutenant Cuyler of Queen’s Company of Rangers came here, and gave me the following melancholy account of his whole party being cut off by a large body of Indians at the mouth of the Detroit River.” Here follows the story of Cuyler’s disaster, and Christie closes as follows: “I have sent to Niagara a letter to the Major, desiring some more ammunition and provisions, and have kept six men of Lieutenant Cuyler’s, as I expect a visit from the hell-hounds. I have ordered everybody here to move into the blockhouse, and shall be ready for them, come when they will.” Fort Presqu’ Isle stood on the southern shore of Lake Erie, at the site of the present town of Erie. It was an important post to be commanded by an Ensign, for it controlled the communication between the lake and Fort Pitt; but the blockhouse, to which Christie alludes, was supposed to make it impregnable against Indians. This blockhouse, a very large and strong one, stood at an angle of the fort, and was built of massive logs, with the projecting upper story usual in such structures, by means of which a vertical fire could be had upon the heads of assailants, through openings in the projecting part of the floor, like the _machicoulis_ of a mediæval castle. It had also a kind of bastion, from which one or more of its walls could be covered by a flank fire. The roof was of shingles, and might easily be set on fire; but at the top was a sentry-box or look-out, from which water could be thrown. On one side was the lake, and on the other a small stream which entered it. Unfortunately, the bank of this stream rose in a high steep ridge within forty yards of the blockhouse, thus affording a cover to assailants, while the bank of the lake offered them similar advantages on another side.
