Extract from Discovering Old Huddersfield (1993-2002) by Gordon & Enid Minter:
Soon after joining Manchester Road notice, on the left, the Warren House inn with its new sign depicting ambush and murder. It is a well known fact that, in April 1812, William Horsfall, arch-opponent of the Luddites, was murdered by them near to the Warren House Inn and that, mortally wounded, he was taken there to die. However, the attack took place half a mile away from here at Crosland Moor and the inn to which Horsfall was taken stood at the side of the old turnpike there. It was probably soon after 1820, when traffic on the old turnpike would be dwindling, that the original Warren House was replaced by the present inn on its much more profitable site. It may well be that the landlord of 1812 transferred to the new building, along with the licence, but today the only connection the Warren House has with the notorious murder is its name.
