Hello,
Just got "The Price of Peace" by Colin Cummings of the shelf, it does have ,on page 188 the details of both the Oxford's. And yes it has -
W/O M. Krwawicz as being the man killed, date 14 June 1945.
Should have got it down earlier
However this raises the question of the CWGC details recorded as there is no record of non Commonwealth deaths on 14 June 1945 on its website.
Great work on your part, well done.
Alex
