Hello,
For the answer to your question, go to the index between pages 663-704 and match up the losses on 01/04/1940 and 02/04/1940. Doesn't seem to be any entries missing.
01/04/1940
Demon K8216 -Index p.670
Harvard N7308 - Index p.673
Wallace K6014 - Index p.703
Oxford L4569 - Index p.687
02/04/1940
Hind K4654 - Index p.675
Hind L7201 - Index p.676
Of course, if Colin (or the printer) missed a few, they might very well not be indexed at all.
Col.
