Provisional Handbook of the Chaser Mark I

In 1916 the British Army had started using tanks in battle in an attempt to break the deadlock of trench warfare. These large lumbering Heavy Tanks were slow and unable to exploit weaknesses in enemy lines or a breakthrough. What was needed was a new 'Medium' Tank, and the Lincolnshire firm of William Foster and Co., the brains behind the Heavy Tanks set to work on a new Medium vehicle. By February 1917, this new vehicle, known as the Tritton Chaser or 'Whippet' was ready in prototype form. Two hundred of these Whippet tanks, officially known as the Medium Mark A were produced. This manual dates to the early days of the Whippet as it was being produced for the Tank Corps. A guide to the operation and maintenance of this new, smaller, and faster tank.
