Battle of Saint-Gilles
Revolt of William IV of Auvergne against Philip I · Not locatable as a sourced battlefield — the corpus “Saint-Gilles / Camargue” narrative has no matching Wikipedia article
Summary
In 1082, Philippe I descended into the Bas-Rhône to secure the rich abbey of Saint-Gilles and the royal tolls surrounding it. William IV of Auvergne, allied with the Languedoc barons hostile to the king, tried to take the city by surprise but came up against the royal garrison. Philippe rushes with a host made up of Ile-de-France knights and Provençal auxiliaries, overthrows the Auvergnats to the south of the town and captures Guillaume after a chase into the marshes of the Camargue.

Historical context
Since the end of the 1070s, William IV of Auvergne took advantage of the king's difficulties to extend his influence southwards, controlling the pilgrimage routes and contesting the Capetian control over the revenues of Saint-Gilles. The abbey, close to the Count of Toulouse, requested royal intervention. Philip I then gathered reinforcements from the viscounts of Narbonne and the Provençal houses loyal to the Capetians, while William brought together contingents from Auvergne and Rouergat to hold the right bank of the Rhône.

Tactics
Major correction (as tet/bidossa/moncontour): no FR/EN Wikipedia page “Battle of Saint-Gilles (1082)”. The narrative (Rhône fords, Provençal crossbowmen, capture of William IV of Auvergne in the Camargue) is not encyclopaedically sourced. Attested 1082 fact for Philip I: annexation of the Vexin in reprisal for Robert Curthose’s attack aimed at William Rufus (English Wikipedia Philip I of France). Saint-Gilles abbey exists (pilgrimage, papal links) but no royal 1082 battle is documented on Wikipedia. Corpus strengths and tactics removed as unattested.
Consequences
The capture of William IV led to his detention in Sens and then an agreement of submission: he returned the seized tolls and swore loyalty to the king. Philippe imposes royal provosts in Saint-Gilles and strengthens the Capetian alliances in Languedoc. The failure of the uprising discouraged Auvergne autonomist aspirations for a generation and consolidated Capetian prestige on the Rhône axis.
