Relating in part to ''Flying Colors'', the act of ''Nailing The Colors'' was a practice of Naval Warfare which goes back to the 17th Century AD. Naval combat on The Sea served the goal of sinking an Enemy Ship or forcing it to capitulate (surrender). In many Navies, the act of Surrender was ''unheard of''. A Sailor at War was expected to ''go down with His Ship'', unless ordered otherwise. The main goal of forcing capitulation was to shoot away (The Flag) or compel an Enemy to ''lower'' same. The supreme ''Act of Defiance'' was for a Captain to order His Flag to be ''Nailed to The Mast''. This meant that The Ship had no intention of surrender and would in fact, fight to the last man and sink.
