It was in January 1770, whilst Weeden and Smith were still debating vainly on what, if anything, to think or do about the whole bewildering business, that the incident of the Fortaleza occurred. Exasperated by the burning of the revenue sloop Liberty at Newport during the previous summer, the custom fleet under Admiral Wallace had adopted an increased vigilance concerning strange vessels; and on this occasion His Majesty's armed schooner Cygnet, under Captain Harry Leshe, captured, after a short pursuit one early morning, the scow Fortaleza of Barcelona, Spain, under Captain Manuel Arruda, bound according to its log from Grand Cairo, Egypt, to Providence. When searched for contraband material, this ship revealed the astonishing fact that its cargo consisted exclusively of Egyptian mummies, consigned to "Sailor A. B. C.", who would come to remove his goods in a lighter just off Nanquit Point and whose identity Captain Arruda felt himself in honour bound not to reveal. The Vice-Admiralty Court at Newport, at a loss what to do in view of the non-contraband nature of the cargo on the one hand and of the unlawful secrecy of the entry on the other hand, compromised on Collector Robinson's recommendation by freeing the ship but forbidding it a port in Rhode Island waters. There were later rumours of its having been seen in Boston Harbour, though it never openly entered the Port of Boston.
