Whatever the truth is about the reason for Sackville's inertia at Minden, it should not detract from the ever lasting glory for British arms earned by the six infantry battalions in the centre of the Allied line. It's been said at times that the British army consists of "Lions led by donkeys", (certainly true during WW1 IMHO) - from what I've read in various sources, Sackville certainly fits that description.
I think you will find that the ‘lions led by donkeys’ concept developed in the 1960s when a lot of anti-war ‘philosophy’ centred on WWI. If you consider what the generals of the time were dealing with, in terms of technological advances, especially in defensive warfare, then the problems of how to take a position at that time, given the technology of the attacker, become all too evident. The Germans had exactly the same problem, as attackers, at Verdun. Unfortunately it took four years for the technology and tactics of the assault to overtake those of the defence - too late for an exhausted Germany, but not for the Allies with 2 million additional US troops, more reliable tanks and light machine guns. I fear that the last four years of remembering WWI is very much in danger of going back down the over-emotional route seen in the 60s. In war people die; in big wars many people die. Let’s not forget that more British people died at the battle of Towton in 1461 than Britons on the first day of the battle of the Somme.
