The capture of the Havana produced a “sensation” in the North-American colonies.  The news was a month in reaching this part of the country, and Philadelphia, the most important place in British America, had the pleasure of first hearing it in fourteen days from the seat of war.  It was “expressed” to New York, which town got it on the 11th of September; and it was published in the Boston “Gazette” of Monday, September 13th, the same day on which our ancestors were gratified by the publication of the London “Gazette” Extraordinary giving a detailed account of Prince Ferdinand’s victory at Wilhelmsthal, on the 24th of June.  There is not a line of editorial comment, but the news is clearly and vigorously given, special mention being made of the spoil, which included, according to one authority, fourteen million milled dollars.  It is stated, in conclusion, that “the Spanish families that had withdrawn from the city to the country were all returned with their baggage, and were in possession of their habitations; and some soldiers and English Negroes were hanged for committing some small thefts on them.”  In the “Gazette” of September 20th there are published some details of the operations in Cuba; and under the “Boston head” is a brief account of the rejoicings that took place in Boston, on the 16th, in honor of the great event, and of British successes in Germany.  “In the morning,” says the account, “His Excellency, [Governor Bernard,] accompanied by the two Houses of Assembly, attended divine service at the Old Brick Meeting House, and a sermon well adapted to this joyful occasion was preached by the Rev.
