On a beautiful spring day with the temperature easily in the 60’s, we decided on a quick drive up to the Arras battlefields and had a pleasant walk around the south east side of Monchy, covering the area around Bois du Sart and Bois du Vert, The Mound and Infantry Hill. On the way we stopped off at the two German blockhouses at Wancourt and two cemeteries, Henin Communal Extension and Wancourt British Cemetery. Above: Images of the larger blockhouse, presumably a command post that was built for defence with several embrasures. The entrance and an embrasure can be seen in the first image. Interior images are poor as my cameras flash decided not to work!! ABOVE: HENIN COMMUNAL CEMETREY EXTENSION, HENIN-SUR-COJIEUL (P. De C.). 5 miles S. of Arras, 2 ½ miles NE. of Boyelles Sta., 750 yards S. of village, near St. Leger road. Henin was 1 ½ mile behind front line at beginning of Battle of Arras April 1917, and was used from April to Nov. 1917....
