Thanks for that. I take it you mean the British CWGC Cemetery on the D339 - Duisans British Cemetery? Are you absolutely sure as I don't want to go into print with the wrong info! There is another bit you can help me with which involved the action on 21 May 1940. At Dainville Captain Davis Hunt plus a detachement of Y Coy 4/RNF ambushed a German column in the sunken road just south of the D59 where it passes under the railway. Problem is that there are two roads which do this, one which appears to be unmetalled and the other - just to the south of it - which appears to be the minor road from Berneville. Any idea which one is Hunt's sunken road? Jerry
