Charles Ward, however, discovered another vague sidelight in some Fenner correspondence which he found in New London, where he knew another branch of the family had lived. It seems that the Fenners, from whose house the doomed farm was distantly visible, had watched the departing columns of raiders; and had heard very clearly the angry barking of the Curwen dogs, followed by the first shrill blast which precipitated the attack. The first blast had been followed by a repetition of the great shaft of light from the stone building, and in another moment, after a quick sounding of the second signal ordering a general invasion, there had come a subdued prattle of musketry followed by a horrible roaring cry which the correspondent, Luke Fenner, had represented in his epistle by the characters "Waaaahrrrr—R'waaahrrr". This cry, however, had possessed a quality which no mere writing could convey, and the correspondent mentions that his mother fainted completely at the sound. It was later repeated less loudly, and further but more muffled evidences of gunfire ensued; together with a loud explosion of powder from the direction of the river. About an hour afterward all the dogs began to bark frightfully, and there were vague ground rumblings so marked that the candlesticks tottered on the mantelpiece. A strong smell of sulphur was noted; and Luke Fenner's father declared that he heard the third or emergency whistle signal, though the others failed to detect it. Muffled musketry sounded again, followed by a deep scream less piercing but even more horrible than those which had preceded it; a kind of throaty, nastily plastic cough or gurgle whose quality as a scream must have come more from its continuity and psychological import than from its actual acoustic value.
