Tugs or minesweepers in the Mediterranean RMG PW1145, William Lionel Wyllie, 1915 ?

Tugs or minesweepers in the mediterranean signed by artist, lower right. Wyllie completed many drawings relating to the mediterranean, especially the dardanelles campaign during 1915, but whether he did subjects there later in the war remains to be confirmed. The received title of this one was simply 'minesweepers in the mediterranean', but the vessels depicted are not fleet minesweepers or trawlers. The minimal mast, small size and single funnel indicate that they may be tugs. Alternatively, they may be dance-class tunnel minesweepers intended for inshore and river work. This class was built in 1917-18, ten being in service during 1918, but not apparently in the mediterranean. It is a fine watercolour and its exact subject may become clearer if the distant coastline can in due course be identified. Date: 1915 ?. Dimensions: 115 mm x 246 mm. Collection: Fine art.
