This atmospheric work by Cull vividly depicts the purpose as well as the very essence of ‘dazzle-painting’. With the sole exception of the destroyer shepherding the convoy, all the other vessels seem to merge betwixt sea and sky as if to endorse the conception itself. Conceived by the prominent marine artist Norman Wilkinson (1878-1971) whilst he was serving as a Lieutenant in the Royal Naval Volunteer Reserve in 1917, the idea behind the so-called ‘dazzle-painting’ of ships was to confuse enemy gunners and, more especially, enemy submariners into miscalculating a vessel’s course and speed so as to lessen its vulnerability as a target. Experimentation rapidly proved it to be a brilliant concept and it was soon adopted by the Royal Navy as well as the Merchant Marine for whom it was originally intended. Its success also brought Wilkinson to official notice to the extent that, when the Second World War began in 1939, he was appointed Inspector of Camouflage with the somewhat curious rank of Air Commodore whilst continuing with his principal employment of painting.
