East Yorkshire Yeomanry- War Diary
The East Yorkshire Yeomanry (E.Y.R.) joined the B.E.F. in April 1940 having crossed the English Channel via Southampton to Le Havre; the same harbours and route taken by the 140th Field Regiment the previous month.
The E.Y.R. had advanced into Belgium with the main thrust of the British advance into Belgium on 10th May 1940 and withdrawn via Tournai and Lille to join the 145th Brigade ‘Somerforce‘ at Cassel, arriving there on 26th May 1940.

The E.Y.R. took up positions on the Mont des Recollets, sharing this site with the Chateau Masson HQ and three Gun Batteries of the 140th Regiment in the perimeter of the woods. Mont des Recollets was heavily wooded and it appears that the trees provided good cover from the incessant German mortar attacks- shells would detonate in the tree canopies before causing serious damage to the ground below.
The position at Mont des Recollets became untenable by 28th May 1940 and the E.Y.R., together with 140th Regiment and others, had to withdraw to the garrison town of Cassel itself.
The War Diary of the E.Y.R. provides a graphic account of the Battle of Cassel and is reproduced verbatim here:-
