The War of Savoy
Part 3: the Offensive
The War of Savoy was a trans-formative moment for French military doctrine, which was already unique as it was. It's hard to estimate how much of a head start that France got out of de Villenueve (
Roughly a 300 year headstart, as I have only recently realized how revolutionary Clausewitz and the mere idea of strategic doctrine was). His idea of a defensively oriented army which actively engaged in increasing enemy attrition as they approached both anticipated the concept of defense in depth and the strategy of guerrilla warfare. But after de Toqueville's utterly failed defense of France in 1561 completely poisoned the concept of defensive warfare in France for a generation.
Why did Villenuevan strategy fail so painfully under de Toqueville? There were two reasons for this, one of doctrine and one of implementation. I will deal with the problem of implementation first because it's more obvious.
De Toqueville failed at a defensive strategy because he only implemented half of such a strategy: he waited in place with his heavy infantry, but he didn't interdict his enemy's supply lines, he didn't scout out the enemy positions or maneuver his army to cut off enemy advances. De Toqueville, being trained during the golden age of Villenuevan thought, clearly understood that the defense was about waiting, but he didn't realize the other side of this--that defense is about preparation, and about actively wearing down the opponent as they come to you.
But there was also a basic doctrinal error in Villenuevan thinking: it didn't account for the political cost of a defense. There was nothing that would say that Poperinge would hold after several other forts fell before Austrian guns, and there's nothing to say that Villenuevan doctrine wouldn't be rightly criticized when it led a general to leave the garrisons to their enemies, alone and isolated (
This really is my only real issue with Clausewitz, but then Clausewitz was very aware that he was writing for generals rather than heads or state, and he knew that it wasn't the generals place to decide on political matters, so in the end it's not a real problem).
But these weren't body-blows. These were problems with Villenuevan doctrine, which were ameliorated to some degree by Louis XI and Henri II, but the real deathblow to Villenuevan doctrine (at the time) was the colossal success of Louisian warfare during the second half of the War of Savoy.
Louis XII is generally shown in the armor he wore during the War of Savoy. The image of Louis XII as the conqueror would influence French politics for centuries after his death
Louis took command of a Northern Corps in shambles. The Armee de Bourbonnais had been destroyed in the Battle of Barrois, and the other two armies were so below battle strength that they had to retreat to Normandie and Brittany to reinforce. Worse still, the armies of Liege, Trier, and Austria were now only a stone's throw away from Paris, which was itself undefended except by a series of 4 strongholds along the Loire. The situation seemed dire, untenable. And yet Louis remained calm and analytical. He realized that he only had 15,000 men at his disposal at this point--5,000 cavalry, 8,000 infantry, and 2,000 gunners and support troops guarding several supply convoys and roughly 50 guns. For the next 6 months, this was all that he effectively had--the other armies within the corps would take until the mid-summer to reorganize, so Louis was on his own. With this army, Louis had to defeat the ~50,000 soldiers of the Austrian coalition who were positioned within France.
Worse still, he had deprived himself of his best leadership. The Prince de Chaumond and the Comte Tulle were both given command of the other armies in the Northern Corps, which left Louis with an experienced though mediocre staff. The only general of note left in Louis' army (besides Louis himself) was the Comte de Maurepas, son of a long line of French commanders. De Maurepas was an exceptional infantry commander, and one of the few infantrymen in the early 16th century who truly understood the impact of the musket and arquebus.
With the obstacle's in place, Louis moved on to his short-term goal: the defeat, piece by piece, of the Imperial Coalition. Louis' first goal was to bring about the surrenders of the bishoprics of Trier and Liege. Both enemies, though small, were highly dangerous, for totally different reasons. The Archbishopric of Trier had developed along the Rhine for the last several centuries, and over time the bishops of Trier had allowed certain degrees of usury, which led to an explosion of the Treiran merchant class. The merchant houses of Trier were one of the main backers of the coalition's side of the War of Savoy, and without Trier Austria would be greatly weakened. On the other hand, Liege, which had been utterly surrounded first by the Duchy of Burgundy and then by the Kingdom of France and the Archduchy of Austria, had taken to overdeveloping their military, until in 1560 the Liegian army was one of the most disciplined, hardened forces in the world. Furthermore the weakness of the Liegian aristocracy had led to a meritocratic officer system in Liege which led to top-rate generals.
With this said, Louis had two massive advantages on his side, which he used with gusto. The invention of the corps system of separate armies converging on one point gave the French military far more flexibility against the armies of her enemies, and the fact that Louis was operating in French territory allowed him to make do without supply lines and buy food for his army directly from the people. With these two advantages in place, we can see how it was that Louis was able to advance from Savoy to Orleanais to Valencies and Barrois within 3 months time (a devilish speed for an army at the time), and also how Louis managed to create such decisive victories against his opponents.
The situation in the summer of 1561
The first opponent was the Liegian army, which posed the most danger as the most mobile force. The battle of Valencies I will deal with in depth because it shaped Louis' tactics greatly and because most other battles in the summer and fall of 1561 occurred in a similar fashion. Louis, attacking a 6,000 man enemy, split his armies into three groups--two infantry groups (one of which was commanded by de Maurepas), which engaged the enemy one after the other, and a 5,000 man cavalry reserve which would deploy in plain sight and be controlled directly by Louis. Holding his cavalry in reserve set the Liegian Bishop-General highly on edge--he knew that at any moment the cavalry could be ordered to charge, and so he adopted a far more conservative tactic than he would have against a mere 5,000 man force. When he realized that there was a third army of infantry, he ordered that his army fall back, after which Louis ordered a charge. The battle, though seemingly unimportant militarily, showed the coalition how skilled a general Louis was, and this reputation became a key factor soon after.
From Valencies, Louis moved on to Barrois, where he scored a victory against the Army of Trier. The battle of Trier involved a similar dynamic to the Battle of Valencies, but Louis used his cavalry far more aggressively, charging all at once into the opponent's flanks. This tactic broke the Trierian army and sent them retreating all the way to the Rhine, leaving Trier completely unguarded. The Archbishop met Louis at the Franco-Trierian border on August 12th, negotiating for a white peace. Louis managed to get a slightly better peace deal, which led to Trier leaving the war and renouncing subsidies to the rest of the coalition. This, along with the message Louis read on the 13th that the Armees du Nord/du Flandres were ready to march led to the end of one 'phase' of the war, marked by an Austrian offensive, and led to the second 'phase', wherein Louis used his messanges to conduct a massive war of maneuver against the Austrian generals.
The Battle of Barrois added greatly to Louis' reputation as a nigh-invincible commander
Out of these battles came a group of cavalry commanders who would dominate the French military for a generation. De Baumanhaise is the most recognizable of these commanders, but there were nearly 20 other men who served in the cavalry of the Armee Royale who became senior officers in the French military. Their edict of corps-based, decentralized, offensive warfare became a way of thinking that all Frenchmen applied to the military, to the degree that talk of 'initiative' (the favorite word of these commanders) became used in the common vernacular of the townsman, merchant, and intellectual.
Now that the Corps du Nord was ready for battle, the first goal was to defeat the Armee der Nederlanders (led by the Duke of Luxembourg), which posed a fatal threat to Paris. The Duke of Luxembourg was, by all accounts, a great general, but his experience came, almost entirely, from putting down Hungarian revolts and fighting minor German states. He (and by extension his army) had never fought an army larger than his, and he was rightly horrified of Louis' reputation by this point (especially considering how far away from the Austrian lines the Armee der Nederlanders was), and so he sent all his scouts out to see when the Armee Royale approached. When his scouts found (in September) that the Armee Royale was marching on his position, the Duke of Luxembourg chose to fall back towards the Austrian front line, which is when he was attacked by the Armee du Nord (led by Prince de Chaumond). The Duke of Luxembourg did his best to keep up a steady withdrawal while being beset on all sides by the Corps du Nord. Finally Louis XII was able to force the Duke of Luxembourg into battle with his back to the Meuse river. Forced into the river by the force of French arms, the Duke of Luxembourg died, pierced by an epee, on the border of his own fiefdom.
The Battle of the Meuse completely ended the Austrian offensive into France
With the desruction of the key parts of the Austrian offensive in the late fall of 1561, Louis wintered on the border to the Austrian Netherlands while Matthias I retreated to Amsterdam, the only city in the Duchy of the Netherlands which could sustain the Armee der Vlandren. 1562 saw a reversal of fortunes, as French troops invaded the Occupied and Austrian Netherlands, reaching the Rhine by may, and surprising/destroying many recently raised Austrian regiments.
The major battles of 1562
This good news was supported with further good news: a message by the Duke of Milan announced that he had negotiated the Treaty of Savoie during the summer, which gave the Kingdom of France her claimed territories as well as a massive share of the Savoyard treasury. The Duke of Milan then stated that his next objective was the conquest of Tyrol.
The picture wasn't completely rosy, though. As 1563 dawned, it quickly became clear to Louis that the Armee der Vlaandern wasn't the only threat. The increasing fiscal and social unraveling of the realm was soon coming into play, and things would only get worse on that front while the war waged on.
note: There were two separate games here, one in which my computer overheated and the one that I ended up finishing. The overheated one featured the death of de Toqueville (he's still alive, and he has yet another embarrassment coming up), a high-fire Louis, and Austrians at Cambray. The actual game had a high-maneuver Louis (which makes more sense given he was a cavalry captain) and a more cautious Austrian AI (I also messed up in the overheated game by not setting my military maintenance to the highest before the war leading to several major losses)
