DescriptionBritish Mark I male tank Somme 25 September 1916 large.jpg
An early model British Mark I "male" tank, named C-15, near Thiepval, 26 September 1916. The tank is probably in reserve for the Battle of Thiepval Ridge which began on 26 September. The tank is fitted with the wire "grenade shield" and steering tail, both features discarded in the next models.
