With the loss of Susa at the end of the campaign of 1707, the defence of the alpine frontier became more difficult for the French. The Saint-Martin Valley, the Pragelas Valley, Perosa (probably Perosa Argentina), Upper Dauphiné and Savoie were now exposed to invasions.

The Maréchal de Tessé had 80 bns and 60 sqns posted along the frontier. Most of these units were understrength, and Tessé was facing an Allied army of 105 bns and approx. 15,500 horse. Tessé wanted to recapture Susa as soon as possible.

The Allies were deployed as follows:

  • the Savoyard Army was stationed in Piedmont;
  • 10 bns and a detachment of approx. 1,500 German troops occupied Susa and were busy improving the defensive works of the place;
  • the Imperial Army and the contingent of the Holy Roman Empire were stationed in Lombardy; however, their strength were diminished since the departure of the Hessian Contingent for Germany, the departure of 2,000 Imperial troops to reinforce the army of Count Daun in the Kingdom of Naples and the embarkation of 6 Austrian bns and 11 Palatine bns for Catalonia at Finale and Vado on 1 January 1708.

During winter, the Comte de Medavi assumed command in Dauphiné and Savoie, while the Maréchal de Tessé sojourned at the Court in Versailles. He instructed his subordinates to take the following dispositions:

  • M. de Thouy improved the entrenched camp of Bourg-Saint-Maurice at the foot of the Petit Saint-Bernard, as well as the entrenchments of Modane and those blocking access to the Mont-Cenis passes.
  • In Dauphiné. Toralba and Caraccioli entrenched Oulx, Fenestrelle and Exilles, and Muret improved the entrenchments of Perosa and put some regions of Piedmont to contribution.
  • M. Le Guerchois put the Stura Valley to contribution and improved the entrenchments and outposts of Barcelonnette.
  • In Provence and the County of Nice, M. d'Artaignan established outposts on the coast between Marseille and the Var River, and broke all roads used by the Allies on the previous year to invade Provence.

The Duke Victor Amadeus of Savoy raised militia in all his estates. The Imperial generals raised militia in Lombardy and sent some weak regiments back to Germany. These units were replaced by new regiments. Recruits and remounts arrived from Germany. Two cavalry rgts came back from the Kingdom of Naples.

In March, the French received intelligence that the Duke of Savoy planned to lay siege to Exilles and to make a diversion towards Perosa and that the field army of the Allies would consist of only 23 bns

  • 15 German bns of 900 men each, deployed in the Susa Valley between Susa and Turin
  • 6 bns in the Aosta Valley
  • 2 bns covering the line of communication between Cuneo and Saorge

The Guardie of the Duke de Savoy, along with 2 cavalry rgts and 3 dragoon rgts were in the vicinity of Pinerolo, while the main magazines were located in Turin, Susa, Avigliana, Ivrea and Saluzzo. There were now only 10 Imperial infantry rgts and 13 cavalry rgts in Italy, excluding the Prussian Contingent and the corps stationed in the Kingdom of Naples.

The Comte de Medavi was informed that the Duke of Savoy was assembling a train of 25 heavy artillery pieces in Turin which should soon march to Susa. Medavi instructed the troops posted near Oulx and Perosa to be ready to march.

On 28 March, the Duke of Savoy and Field Marshal Count Starhemberg arrived at Susa and reconnoitred the vicinity of Exilles.

On 22 April, Count Starhemberg embarked at Genoa for Catalonia.

At the end of April, Louis XIV decided that the Duc de Bourgogne would command in Flanders; Elector Max Emanuel of Bavaria, on the Rhine; the Maréchal de Villars, in Dauphiné, Savoie, Provence and in the County of Nice; the Duc d'Orléans, in Spain; and the Duc de Noailles, in Roussillon.

At the end of April, Louis XIV recalled 21 bns and 40 sqns from Dauphiné and Savoie, leaving only 74 bns and 20 sqns in these provinces:

  • 41 bns in Dauphiné
  • 12 bns and 12 sqns in Savoie
  • 21 bns and 8 sqns in Provence and in the County of Nice

On 6 May, M. de Medavi, informed that the Allies were assembling an army at Susa, transferred 10 bns and a few guns from their quarters to take position on the frontier of Dauphiné.

On 8 may, when Medavi's 10 bns arrived on the frontier, M. de Toralba, who commanded at Oulx, reinforced his outposts, placing 1 bn at the Lambournet (unidentified location) and 1 bn at Ramats.

On 9 May, M. de Toralba and M. de Muret reconnoitred the Pragelas Valley (present-day upper part of the Val Chisone) and the Fenestrelle Pass, which was still buried in snow. Nevertheless, Toralba reinforced the redoubt with 20 grenadiers and posted 100 men in the neighbouring barns to support the redoubt. He also advanced 1 bn to Balboutet, and 3 bns close to the Fenestrelle Pass to support its defenders.

On 14 May

  • French
    • The French generals were informed that 8 Savoyard bns had taken position between Chaumont (present-day Chiomonte) and Susa, and that the Allies were assembling 4,000 men in a camp at Avigliana.
    • The Comte de Medavi personally went to Oulx. He also sent orders to M. de Thouy, who commanded in Savoie, to assemble his troops at Conflans and to take position at Modane in the Maurienne Valley. Medavi also sent 2 dragoon rgts, 1 cavalry rgt and 4 bns to reinforce the 5 bns already posted in the Maurienne Valley.

On 19 May

  • French
    • M. de Thouy went to Saint-Jean-de-Maurienne to assemble the troops sent by Medavi, which were gradually arriving there.
    • Medavi inspected the defensive works recently erected at Exilles and on the heights of Jalas (unidentified location). He considered that Exilles was the only position which could prevent the Allies from invading the provinces of Dauphiné and Savoie.

On 21 May, M. de Medavi returned to Briançon.

In the night of 21 to 22 May, M. Le Guerchois advanced form the region of Barcelonnette with 500 men to raise contributions in the villages of Pontebernardo, Peillaport (probably Pietraporzio) and Sambuco. He returned with 35 hostages.

On 22 May

  • French
    • Medavi sent 1 bn from Mont-Genèvre to Exilles.
    • 1 artillery bn set off from Briançon with 10 artillery pieces, crossed the mountain at Mont-Genèvre and marched towards Cesanne (present-day Cesana Torinese).

On 23 May in Savoie, 8 bns took position in the entrenchments of Modane, detachments occupied the redoubts of Lans-le-Bourg and Termignon, near the Mont Cenis, and all bridges on the Maurienne were mined. Furthermore, 4 bns, 1 cavalry rgt and 1 dragoon rgt were posted in the Tarentaise Valley. The rest of the dragoons were posted at Aiguebelle and M. de Thouy established his headquarters in Saint-Jean-de-Maurienne.

On 24 May. M. de Medavi left for Grenoble where the Maréchal de Villars was expected on 26 May. When he was informed that Villars had been delayed and would not arrive before the first days of June, Medavi left for Savoie to inspect the defences of this province.

On 31 May

  • French
    • In Savoie, Medavi arrived at Saint-Jean-de-Maurienne. There, he was informed that the Allies planned to assemble a corps of 30,000 men in the vicinity of Avigliana and Rivoli, another corps of 6,000 men near Pinerolo, and a corps of 4,000 men in the Aosta Valley. These various corps would consist of 20 Savoyard bns, 25 Imperial bns, 11 Prussian bns and 10,000 horse. Medavi slightly rearranged Thouy's positions, leaving 8 bns in the entrenchments of Modane, sending 1 dragoon rgt to Saint-Jean-de-Maurienne, 1 dragoon rgt to Conflans, 2 bns, 1 dragoon rgt and 1 cavalry rgt to Bourg-Saint-Maurice in the Tarentaise Valley. Finally, 2 bns were sent to the regions of Chablais and Faussigny.
    • In Provence, M. d'Astier began the construction of a redoubt at Rocca-Taillada (unidentified location) to prevent the Allies from using this road to invade Provence as they had done on the previous year.

M. de Muret, informed that the Prince of Württemberg had just arrived at Susa and that the Duke of Savoy should join him there, advanced troops in the Saint-Martin Valley and Pragelas Valley.

On 5 June in Provence, work began on entrenchments along the Var River, particularly at the mouth of the river, at Saint-Laurent, at the Fort de la Baronne and Fort de Saint-Estève, opposite Saint-Isidore.

On 7 June, the Maréchal de Villars arrived at Grenoble where he received a report from the Comte de Medavi of the dispositions already taken in Dauphiné and Savoie. There was a total of 74 bns and 20 bns:

  • 12 bns and 12 sqns in Savoie, guarding all the passes by which the Allies could invade the provinces
  • 38 bns in Dauphiné
  • 3 bns in the Barcelonnette Valley
  • 12 bns and 8 sqns in Provence
  • 7 bns garrisoning Nice, Villefranche and Montalban
  • 2 bns in Monaco

The Maréchal de Villars entrusted M. de Medavi with the defence of the Province of Savoie and sent 8 additional bns to this province.

On 9 June, M. de Medavi wrote to M. de Thouy to confide him the defence of the Tarentaise Valley while he himself would assume command in the Maurienne Valley.

On 12 June, Villars wrote to Louis XIV to inform him of the situation in the Alps and to ask for a reinforcement of 60 sqns and 30 bns.

On 15 June, Villars went to Oulx to reconnoitre the frontier and to hold a council of war with Medavi, Chamarande, Toralba, Montgon, Dillon, Muret, Tessé and Angervilliers.

On 17 June, Louis XIV informed Villars that he could not send him much reinforcement and that he had ordered to form an entrenched camp at Toulon which would be occupied by a small reinforcement of 8 bns sent from Roussillon and Languedoc. Furthermore, he sent 1 dragoon rgt from Languedoc to Provence. Villars was now at the head of 82 bns and 23 sqns.

On 21 June, M. de Medavi left the region of Oulx to assume command in Savoie.

On 22 June, Villars left the region of Oulx to visit the Pragelas Valley, Fenestrelle, Perosa and the Saint-Martin Valley. When Villars visited Perosa, he ordered M. de Muret to retire from this post, leaving only 400 men for its defence, as soon as the Allies would advance from Susa, and to evacuate the Saint-Martin Valley.

On 24 June at Fenestrelle, Villars was informed that the Duke of Savoy was advancing some troops towards Mont-Cenis. He sent orders to Beauvoisis Infanterie (2 bns), posted at Cagnes, to march to Cesanne before 12 July.

On 25 June, Villars asked M. d'Artaignan to send 7 bns and 2 sqns to Entrevaux, Colmars and Sisteron, and to take position at Colmars with the rest of his corps.

On 30 June, 2 French bns marched from Cagne towards Colmars.

By 1 July, Villars already knew that a corps of 12,000 Imperialist troops was marching towards Rivoli, Avigliana and Orbassano in Piedmont, while another corps of 8,000 men was advancing towards Ivrea and 4,000 men were marching from Avigliana towards Bussoleno. Could Daun had reached Turin to take command of these Imperialist troops. He was himself subordinated to the Duke of Savoy. Furthermore a Savoyard corps of 4,000 was encamped at Orbassano, another of 4,000 men in the Aosta Valley and 8,000 men in the vicinity of Susa.

    • In Provence, 2 bns of the 8 bns arriving from Roussilon and destined to the entrenched camp of Toulon, reached Aix-en-Provence where they were instructed to redirect their march towards Marseille. The first elements of 6 remaining bns and the dragoon rgt were expected at Aix-en-Provence on 9 July.

On 5 July, the Prince de Monaco marched with 50 dismounted dragoons towards Sospel, which was defended by 150 foot.

  • 18,000 men at Orbassano
  • an entire corps at the entry of the Aosta Valley
  • an entire corps at Ivrea

These dispositions confirmed Villars in his belief that the Allies were planning an offensive in Savoie or Dauphiné. He ordered M. d'Artaignan to advance to Barcelonnette with the 7 bn he had with him at Entrevaux and Colmars.

On 7 July, Villars received intelligence that the Allied army consisted of 41,900 men, excluding the 6,600 men employed at the blockade of Ferrare, the rgts destined to Catalonia and 11,000 Savoyards employed as garrisons. He sent 2 additional bns to reinforce Medavi's Corps.

On 12 July, M. de Guerchois sent 3 bns from the camp of Tournoux to Saint-Crépin and Guillestre. However, M. d'Artaignan received orders from the king and Villars instructing him to retire from Barcelonnette to Entrevaux with 5 of his 7 bns.
