The Battle of Almanza took place on April 25th 1707 during the War of the Spanish Succession. It was fought between the armies of France and Spain on the one side and Britain and Portugal and their allies on the other. Although the Franco-Spanish forces won the day, great bravery was shown by the men of the Royal Norfolk Regiment in covering the retreat. In recognition of this heroism, Queen Anne honoured the Regiment by awarding it the badge of Britannia to be displayed on its Colours.
The Royal Norfolk Regiment was amalgamated into 1st Battalion The Royal Anglian Regiment in 1964. The 1st Battalion (nicknamed the "Vikings") still wear as its collar badge The Royal Norfolk Regiment's Britannia superimposed on The Suffolk Regiment's castle and key of Gibraltar.
