One for the surplus fans. In 1917 the British and ANZAC forces in what is now Israel were runnning out of water. While the British and New Zealanders had tried to take the town for months, a last ditch attempt was devised using the Australian Light Horse.
Expecting the Australians to advance within a mile, dismount and attack on foot, as they normally did, the Australians mounted the last succesful Cavalry charge in the history of modern warfare - In three hours they achieved what the British Army had been attempting for three months.
Ironically, all Australians know about Gallipoli, possibly one of the greatest disasters of WWI, but nobody knows of the amazing achievements by the Light Horse in the dark days of 1917.
