Charles Sterling and Margaretta M. Salinger. "XIX Century." French Paintings: A Catalogue of the Collection of The Metropolitan Museum of Art. 2, New York, 1966, pp. 98–99, ill., note that Daubigny spent the month of June 1871 in Étaples and conclude that this picture was painted there based on a related drawing inscribed "Étaples, boats at low tide" (Daubigny's atelier sale, Paris, May 6–8, 1878, no. 557).

Robert Hellebranth. Charles-François Daubigny, 1817–1878. Morges, Switzerland, 1976, p. 230, no. 699, ill., as "Bateaux échoués à Etaples"; erroneusly lists it in the Ferry sale, Hôtel Drouot, Paris, 1921, no. 55.
Anne Wagner. Memo. September 25, 1979, disagrees with Sterling and Salinger [Ref. 1966] that the site of this picture is confirmed by a related drawing, noting that the drawing is not inscribed and is dated 1876, five years after the painting; asserts that the identification of Étaples rests on the fact that Daubigny was there in June 1871 on his way home from London, where he was in exile during the Commune.
