 Next was Operation Robinson, the Le Creusot raid of 17 October 1942, when 94 Lancasters, led by Wing Commander Leonard Slee of No.49 Squadron RAF, made a dusk attack on the Schneider-Creusot munitions complex in Burgundy, ingressing at treetop height from the Bay of Biscay and recovering to England in darkness, for the loss of only one aircraft.Reconnaissance pilot Tony Hill, whose pictures had done so much for British understanding of enemy radar, was shot down while attempting to take post-strike photographs of Le Creusot on 21 October.
