In 1871 Corot left Paris and the upheaval of Commune life to stay with his biographer and friend Alfred Robaut at Douai in north-east France. This is a view of the marshy landscape around Douai. Four other pictures that Corot started on this trip to the Artois are in the National Gallery: \'The Marsh at Arleux\', \'A Wagon in the Plains of Artois\', \'The Oak in the Valley\' and \'Landscape at Arleux-du-Nord\'. The present sketch is a copy after a nature study by Alfred Robaut painted in May 1871. It is a close copy except for the cottage which is a detail added by Corot.
