HRH The Princess Royal, Princess Anne is the Colonel-in-Chief of The Royal Corps of Signals, assuming the appointment in 1977.

This clip demonstrates The Princess Royal’s long-standing links with The Corps. It sees her watching the Royal Signals’ own motor cycle display team – The White Helmets and driving a SnowCat, similar to the one found in The Museum today.

The archive footage from 1970 references the Centenary.

The Royal Corps of Signals was formed in 1920 and will celebrate its centenary in 2020 but the first troop – C Telegraph Troop, Royal Engineers – commanded by Captain Montague Lambert RE – was formed in 1870.


On 6th September 1935 the King honoured the Corps by appointing Her Royal Highness, Mary, Princess Royal and Countess of Harewood (Victoria Alexandra Alice Mary; 25 April 1897 – 28 March 1965) – to be its Colonel-in-Chief.

Today Her Royal Highness, The Princess Royal, Princess Anne of Edinburgh is Colonel-in-Chief to the Corps, a post she has held for almost forty years.
