The name "tank" was introduced in December, 1915 as a security measure and has been adopted in many languages. William Tritton, stated that when the prototypes were under construction from August, 1915 they were deliberately falsely described in order to conceal their true purpose. In the workshop the paperwork described them as "water carriers," supposedly for use on the Mesopotamian Front. In conversation the workers referred to them as "water tanks" or, simply, "tanks." In October the Landships Committee decided, for security purposes, to change its own name to something less descriptive. One of the members, Ernest Swinton) suggested "tank," and the committee agreed. The name "tank" was used in official documents and common parlance from then on, and the Landships Committee was renamed the Tank Supply Committee. This is sometimes confused with the labelling of the first production tanks (ordered in February, 1916) with a caption in Russian. It translated as "With Care to Petrograd," probably again inspired by the workers at Foster's, some of whom believed the machines to be snowploughs meant for Russia, and was introduced from May 15, 1916. The Committee was happy to perpetuate this misconception since it might also mislead the Germans.
