10 March 1942. London, England.
The fall-out from the recent exercise on Salisbury Plain was still reverberating around the army, even to the highest level in the War Office. General Alan Brooke had Major-General Oliver Leese and Lieutenant-General Bernard Montgomery waiting outside his office. He couldn’t help feel like a head-master about to give two badly behaved pupils ‘six of the best’ for their behaviour.
The exercise itself had done exactly what any exercise should do: have plenty of lessons to learn from. The independence of the Umpires had been undermined by Montgomery, something like the shenanigans with the Mobile Force back in the 30’s. Montgomery had ‘won’ the exercise, but it was clear it wasn’t fair, and in fact, he had very seriously failed in the primary objectives. As an artillery man, Brooke could see that XII Corps’ overwhelming artillery power should have prevented Leese from winning, but, while overwhelming, the Royal Artillery wasn’t a preternatural power as the Umpires would have had it.
The Mixed Division (one Armoured Brigade and two Infantry Brigades) was found to be too unwieldly. Until such time as the Infantry Brigades had enough armoured vehicles to match the speed of the tanks, it was just too difficult to coordinate. The Guards Armoured Division did have its infantry in suitable vehicles, and they managed to take on the Mixed Division piecemeal, even although on paper they were the weaker force.
The most effective formation in XII Corps was 53rd (Welsh) Division, along with 25th Tank Brigade. The army had more experience of tank/infantry cooperation of this nature, and Leese’s counterattack ran out of steam when they came up against the dug in and well-prepared Welshmen, whose artillery did indeed act as a deciding factor.
Montgomery and Leese had a very public spat at the debrief about Leese’s use of signal intelligence. Montgomery’s HQ was identified and attacked because of lax radio procedures. Embarrassed by this, Montgomery had called Leese a cheat in front of Brooke and other senior officers. It had already been made clear that the Umpires had been nobbled by XII Corps, so calling the opposition force commander a cheat was, to Brooke’s mind, the pot calling the kettle black.
The Canadian No 1 Special Wireless Section (Type C) had distinguished themselves during the exercise. If there was one lesson that the army had to take seriously was the need for strict radio security. This type of Wireless Section was to be expanded so that at least every Corps would have one, the only changes was the need to have enough interpreters to listen into enemy conversations. Signals Intelligence was already a known and trusted part of the army’s operations. Brooke had already had the heads of the Intelligence Corps and Royal Signals in to hammer home the message that this needed to be strengthened and sharpened. As well as interception, the Canadians had managed some really good direction-finding results. The RAF’s Intelligence had also been copied into this discussion, part of the reason for Montgomery’s HQ being discovered was the length of time the RAF liaison officers spent guiding in the army cooperation aircraft.
In Brooke’s mind, Leese was no doubt conceited about his Guards Armoured Division being ‘elite’. It was a cheeky move to gain the Canadian Wireless group without letting on, but Montgomery had made a fool of himself. Leese, like Montgomery had done a good job in Flanders in the fallback to Dunkirk, and had previously been one of Montgomery’s instructors at staff college back in the 1920’s. The two men had a fairly good relationship up until this exercise, and Brooke was a bit concerned about Montgomery’s over-reaction.
What was worse, from Brooke’s perspective was Montgomery trying to shift the blame for his loss onto others, rather than taking ownership of his own failure. Whereas his infantry did well, Montgomery hadn’t shown that he had a firm enough command of the use of tanks in his plan. It was a problem throughout the leadership of the army, there just wasn’t a consensus about how to use tanks properly. O’Connor’s example was all very well, but tank warfare in North Africa primarily against the Italians, wasn’t going to be transferrable to Europe and against the Wehrmacht. Until tank doctrine was worked out, then hopefully all senior officers would be on the same page. Working it out in exercises on Salisbury Plain was better than picking up the pieces after a disaster on the battlefield. Therefore, he couldn’t be too hard on either Montgomery or Leese, but he settled himself into the headmaster’s role to give them both a good talking to, and make them shake hands, at least figuratively.
