He was also the composer of many well-known marches. Napoleon's war took on its final end, when the allies of Austria, Prussia and Russia marched into Paris on March 31, 1814 to the tune of the "Pariser Einzugsmarsch". This tune was also used as the climax of 1940 Victory parade of the Germans through Paris.
Although attributed initially to Beethoven, Walch is the composer. Another march by Walch, is the famous "Beethoven Funeral March Number 1" played at the funeral of King Edward VII and also on Remembrance Sunday Services in London each year on the Sunday nearest to November 11. It is played after the playing of the Last Post, and during the Wreath Laying Ceremony.
It is also announced as "Beethoven's Funeral March" on the BBC Television commentary. For a long time, the march was wrongly attributed to Beethoven, and catalogued as WoO= (work without opus number), Anh. 13. The march was played during the procession to the lying in state at Westminster of Queen Elizabeth The Queen Mother, and at the procession to St Paul's Cathedral at the funeral of former British Prime Minister Margaret Thatcher on 17 April 2013.
On 24 March 2015, the second day of the Death of Lee Kuan Yew, this same march was also played by the Singapore Armed Forces Band during the foot procession from the Istana to the Lying In State of Mr. Lee Kuan Yew at the Parliament House of Singapore. Many marches supposedly written for several cavalry regiments by Queen Victoria's consort Prince Albert, who was also the Prince of Saxe-Coburg-Gotha and the Duke of Saxony are actually by Walch, including the British regiment march, the Regimental quick march of the Somerset Light Infantry.
