By 1917 Lavery was growing restless in war-time London and gladly accepted the chance to leave the city when the Duke of Westminster invited him to stay at Landes. He travelled via Paris and Mimizan to St Jean de Luz where he arrived in early April. Amongst several works produced on the trip, the most important group was specifically focused on the harbour there. The horizontal emphasis of the present work, punctuated by the moving ships is highly reminiscent of Whistler's seascapes such as Crepuscule in Flesh Colour and Green: Valparaiso, (1866, Coll. Tate Britain, London) and Symphony in Grey and Green: The Ocean (circa 1867, Frick Collection, New York).
