Historical Short story (How the first tank was designed)

On July 28 1914 Walter Gordon Wilson joined the British navy in the royal naval armored car division and William Tritton joined the British army and was asked to design and build tractors that could pull the very heavy howitzers around battle fields. Later in the war Walter and William meet up to create a armored tractor because all the rivers in them were being shoot out of them and they need more protection so they designed a armored tractor that later became the first tank in World War 1. In 1919 they were credited by the Royal Commission of Awards to Inventors as the inventors on the tank. William Tritton was knighted. They were then best friends for twenty-seven years when Sir William Tritton dies in Lincoln eleven years after Sir William Trittons death Walter Gordon Wilson dies.
