'Royal Marines' 350 Years, is a brief history of the Royal Marines that were formed way back at 11.58 am on Tuesday 28th October 1664 by King Charles II. It describes some of its history up to the present day. Along with its traditions that have moulded Royal Marines into what has always been one of the finest fighting military forces in the world. Those that they fought in battle were so impressed with their courage and skill that their countries formed their own version of the Marines. To copy is the best form of flattery, a way to acknowledge just how great the Royal Marines were respected. Once A Marine Always A Marine.
