In 1871 Corot left Paris & the upheaval of Commune life to stay with his biographer & 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' & ' 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.
