Merci Warbird, anyway:
According Andrew Mollo, The Armed Forces of World War Ii, ed. Military press, N.Y., 1981, pg. 61, there were only 3.457 deads among the about half million of men of the BEF, during the 1940 campaign. Little more than 3.000 of them died when the liner Lancastria was sunk.
Igor wrote, then, some times ago, mentioning 92.000 French deads during the same campaign while the number of 120.000 (or 127.000) includes the POWs who died or disappeared in the 1940-1945 period (or, later, in Soviet hands).
