Lieutenant-Colonel Bernard Barton, who died on 11th August 1918, is buried in Tannay British Cemetery, Thiennes, Nord, France (Plot 5 Row C Grave 4). Rows C, D and E of Plot V contain graves of men, primarily from the 61st (South Midland) Division, who died in the middle weeks of August, as was the case with Lieutenant-Colonel Barton.
The village of Thiennes is about 8 kilometres east of Aire-sur-Lys, which is a town on the N43 between Bethune and St Omer.
It was not until the German offensive of April 1918, by which Merville was overwhelmed and the German line brought past it along the Lys nearly as far as St Venant, that Thiennes became a place of British burials.
The cemetery now contains 363 First World War burials and 18 from the Second World War. The cemetery was designed by Sir Herbert Baker.
