Aerial photograph, St Eloi, near Ypres, Belgium, 27 March 1916. This aerial photograph was taken on 27 March 1916 after the British had exploded six very large mines at the same time, to knock out the German defence before the Allies advanced. The new huge mine craters can be seen looking like four hills in a line up the centre of the photograph.
