'Mightier Yet! Britain's Mechanised Army grows stronger every day', 1940

This propaganda poster depicts a Vickers Mk 2 medium tank. The British Army that went to war in 1939 was almost fully mechanised and very different from its 1914 counterpart which relied on thousands of horses. The cavalry in particular had completely changed. In 1928 the 11th (Prince Albert's Own) Hussars became the first cavalry regiment to mechanise, receiving armoured cars in place of their horses. The other British cavalry regiments followed their lead and all were eventually mechanised by 1941.
