No. 4 Flag at Trafalgar
The Trafalgar signal has been a controversial subject in the past. This article considers whether the number 4 flag, hoisted 3 times in the historic signal, which was a red and white quartered flag, had the red or the white uppermost to the mast. Particular reference is made to the printed Admiralty signal book of 1799, revised in 1803, and whether the book carried by HMS Victory was as used by the Mediterranean or Channels fleets.
