<P> Sea Cadets in the United Kingdom Hold a national Parade on Trafalgar Square each year . The parade is formed with a platoon from each area, a guard and a band . This is held on the closest Sunday to 21 October . Units and Districts from around the country celebrate this day--usually with a town parade . </P> <P> Birmingham celebrates the anniversary with a ceremony at the statue of Lord Nelson--the oldest such statue in the United Kingdom--in the Bull Ring . The ceremony is led by the Lord Mayor of Birmingham and involves men and women of HMS Forward, Sea Cadet units from across the West Midlands and various civic organisations, including The Nelson Society and The Birmingham Civic Society . Afterwards representatives of naval and civic organisations lay wreaths and a parade marches off to Victoria Square, the public square in front of the seat of local government, where the Lord Mayor takes the salute . </P> <P> Another aspect of the Birmingham celebration is that the statue is regaled with swags of laurel and flowers, possibly due to its location by the wholesale flower markets of the city . This tradition, marked through most of the nineteenth century, was revived in 2004 . </P> <P> In Edinburgh, citizens commissioned the Nelson Monument on Calton Hill in memory of Admiral Lord Nelson . Weather permitting, the Trafalgar flag signal "England expects that every man will do his duty" is flown on Trafalgar Day . Looking like a tall stone telescope, the Nelson Monument contains a time ball which drops at 1 o'clock daily . </P>
