'They Were Not Divided' is a little-remembered 1950 film following the fortunes of two Welsh Guards officers, one English the other an American volunteer, in the Guards Armoured Division between 1940-44. The first half covers them kicking their heels in Britain, with exercise after exercise (which was the fate of many troops in the four years after Dunkirk), but the action picks up in the second half, with the breakout from Normandy, the race for Brussels, Arnhem and the Battle of the Bulge. The film really captures the pace of mechanised warfare, and although inevitably it relies heavily on newsreel footage for the combat sequences, it is shot in a verite style so the effect is seamless. Although not strictly a wartime morale booster, it's very much a companion piece to the 1944 classic 'The Way Ahead', which covers similar ground for the infantry, and although the characterisation is rather stilted, the twist in the ending is surprisingly moving.
