That isn’t to say that battlefield tactics hadn’t improved. Quite to the contrary, 1918 saw both the Germans and the Allies deploy far more effective systems for assaulting trenches, though I would argue that it was actually the French who came closest to having the matter as figured out as one could have it with the equipment of 1918. The French method, termed la bataille conduite (“methodical battle”) has an understandably poor reputation because this method failed so badly against the technologies of 1940 but as we’ve seen that was quite a different technological environment than 1918.
On the defensive, the French had adopted many of the same principles of the German defense-in-depth we’ve already discussed. On the offense, they came to favor (particularly under the influence of Philippe Pétain and […] Ferdinand Foch) an offensive doctrine designed to maximize France’s position in an attritional contest: that is to limit losses and maximize enemy casualties while still taking and holding ground. The system favored limited “bite-and-hold” attacks, ideally limited such that the attack stopped before triggering the inevitable German counter-attack. Remember that it was when the attacker ran out of steam and the defender’s counter-attack came that the casualty ratios tended to shift to favor the defender. In French thinking, the solution was just to not reach that point.
Instead, the French came to favor – and the British and Americans picked up the same method by the end – elaborately prepared small offensives. The elaborate preparation meant planning out the attack carefully, using shorter but carefully planned hurricane barrages (all of this planning, of course took time) and then seizing the enemy’s forward positions and just their forward positions. Instead of then trying to push through – the old French notion of assault brutal et continu (“brutal and continuous” – a “keep up the pressure till they break” method) which Robert Nivelle had favored – methodical battle focused on “bite-and-hold”.
Once you hit your limited objectives in that first rush where enemy resistence is disoriented (from the short, hurricane barrage) and weaker – and thus where the casualty ratio favors you – you stop and begin fortifying your position. You dig those communications trenches, move up your artillery and brace for the counter-attack. By the time the enemy realizes you aren’t going to attack his second or third line positions (and trigger his devastating counter-attack), you are dug in and prepared for his attack (the hold part of “bite-and-hold”). To reestablish defense in depth, the defender now has to back up to establish new lines to the rear (or launch his own fresh offensive, but by late 1918, the Germans were too weak for this). A long series of such attacks – with significant intervals for fresh careful planning and stockpiling resources – could slowly but surely lever your opponent off of key positions, one by one. It would also preserve a favorable balance of casualties, ensuring that in the end, the enemy runs out of men and shells before you do (that is the “rupture” that Joffre had always hoped for, but which arrived but two years too late for his career).
Such a slow, expensive, bloody and unglamorous strategy was in some ways only politically possible once, by 1918, it had become apparent that all other options were exhausted. That said, to argue that this bite-and-hold operational doctrine broke the trench stalemate is probably not fair either. The progress of allied offensives in 1918 was extremely slow by even the standards of 1914. The German Spring Offensive was well and truly done in July and the Allied offensive picked up in August and ran through November as fast as it could (with Foch doing everything short of getting out and pushing the offensive to try to speed it up) and yet the final allied positions by November were not even in Germany. Even at its greatest distance in 100 days of unbroken victories by a force with materiel and numerical superiority, the front moved less than 100 miles and the overall casualty ratio was roughly even (around a million on both sides).
