This is the closest to Cambrai Day (20 November), the anniversary of the Battle of Cambrai that was one of the earliest massed deployments of British tanks. On Anzac Day, 25 April, a Wreath Laying Ceremony and Parade is held at the Cenotaph at 11 am, followed by a Service of Commemoration and Thanksgiving at Westminster Abbey. An annual parade and service is also held by the Combined Irish Regiments Association to commemorate the war dead of the Irish regiments that were disbanded on 12 June 1922 after the First World War. This parade is now held on the Sunday in June that follows the Queen's Birthday Parade. The Belgian Parade at the Cenotaph has taken place yearly since 1934 on the Sunday preceding the Belgian National Day (21 July). Belgium is the only nation that is allowed to parade its troops in uniform and carrying arms in central London. The War Widows Association of Great Britain hold their Annual Service of Remembrance at the Cenotaph on the day before Remembrance Sunday. Lutyens' first cenotaph design was for The Cenotaph, Southampton (unveiled 6 November 1920). The temporary Whitehall Cenotaph (unofficial unveiling on 18 July 1919) was followed by the permanent Whitehall Cenotaph (unveiled 11 November 1920). Lutyens' Whitehall Cenotaph design was used in the construction of other war memorials in the UK and in the British Empire. Two smaller versions that included several additions and differences were built as regimental memorials, the Queen's Own Royal West Kent Regiment Cenotaph in Maidstone, Kent, and the Royal Berkshire Regiment War Memorial in Reading, Berkshire. These were unveiled on 30 July 1921 and 13 September 1921 respectively. The Midland Railway War Memorial, Derby, was unveiled on 15 December 1921. The Middlesbrough cenotaph, derived from Lutyens' design, was unveiled on 11 November 1922. The Rochdale Cenotaph was unveiled on 26 November 1922. The Hong Kong cenotaph, an almost exact replica, was unveiled in 1923 between the Statue Square and the City Hall in Hong Kong. The Manchester Cenotaph in Manchester, England (also the work of Lutyens), was unveiled on 12 July 1924 and has similarities and differences. The Welch Regimental War Memorial, in the form of a Lutyens 'Whitehall' cenotaph, was unveiled at Maindy Barracks, Cardiff, on 11 November 1924.
