Lancelot de Mole - an Aussie engineer and inventor - had his place in history compromised by a lack of vision from British authorities. He approached the British War Office in 1912 regarding his idea for “a chain-rail vehicle that can be easily steered and is capable of carrying large loads over various types of terrain all while protecting the passenger.” He submitted further proposals in 1914 and 1916, without any luck.
It wasn’t until 1919, after the British had already used a tank during World War I, that de Mole’s efforts were recognised by a Royal Commission. It acknowledged the importance of his work and noted that had he not been overlooked the British would have had a far better tank at their disposal than the one they constructed without de Mole’s input. The tank would have been built at an earlier date, too. A model of de Mole’s tank can be found at the Australian War Memorial in Canberra.
