`A Moonlight Massacre' - the Night Operation on the Passchendaele Ridge, 2 December 1917

The Third Battle of Ypres was officially terminated by Field Marshal Sir Douglas Haig with the opening of the Battle of Cambrai on 20 November 1917. Nevertheless, a comparatively unknown set-piece attack - the only large-scale night operation carried out on the Flanders front during the campaign - was launched twelve days later on 2 December.
