The ensign was actually used to wrap the coffin on its way to Greenwich:
Quote:
The " Victory," with the remains of the ever-to-be-Iamented Nelson, arrived off Sheerness, Sunday, December 22, 1805.
The body was placed the following morning on board the "Chatham" yacht, proceeding on her way to Greenwich. The coffin, covered with an ensign, was placed on deck. Tuesday she arrived at Greenwich; the body, still being in the coffin made of the wreck of " L'Orient," was then enveloped in the colours of the "Victory," bound round by a piece of rope, and carried by sailors, part of the crew of the " Victory," to the Painted Hall, where preparations were made for the lying in state; the days appointed for which were Sunday, Monday, and Tuesday, January 5, 6, and 7, 1806, and to which all due effect was given. Wednesday, January 8, the first day's procession by water took place, and the remains were removed from Greenwich to Whitehall, and from thence to the Admiralty, with all possible pomp and solemnity. This procession of barges, &c. was nearly a mile long, minute guns being fired during its progress. The banner of emblems was borne by Captain Hardy, Lord Nelson's captain. The body was deposited that night in the captain's room at the Admiralty, and attended by the Rev. John Scott.
Maybe this is what the correspondence quoted by Cowan's was referring to.
