The BEF in Two Retreats: Mons 1914 and Dunkirk 1940

Published on 25 October 2026
Submitted by Prof Gary Sheffield

The Mons (1914) and Dunkirk (1940) campaigns offer many points of comparison and difference. Both were waged by British Expeditionary Forces at the beginning of major wars; they were fought over some of the same terrain; they were a brutal introduction to the realities of modern warfare. However, the technology of 1940 was more advanced, and the circumstances in which the BEF of 1940 fought were more difficult than those of 1914.

In this lecture, Professor Gary Sheffield offers some insights into the two campaigns.
