For three years, the war in southern France remained a punishing stalemate, with General Denis Lakanal barely holding the Pyrenees against the Sultanate of Madjrit. While the French were forced to divert essential resources to the Rhine front, the Madjriti invasion bogged down in the mountains, draining their treasury despite receiving substantial loans from Britain. Domestically, the French Republic teetered on the brink of collapse; the British naval blockade and covert support for rebels fueled hyperinflation and famine, rendering the currency worthless. The ruling Council, dominated by the radical Vanguard faction, responded to the crisis with tyrannical seizures of food and property, maintaining control over a starving populace solely through the threat of state violence.

The strategic balance of the war shifted abruptly in August 1795 with the death of the Madjriti Sultan and the ascension of his son, Abdul Al-Madini. A Francophile who harbored deep resentment toward Britain for its betrayal during the Grand European War, Al-Madini viewed the conflict with France as a waste of resources. In September, he formally switched allegiances, declaring war on Britain and aligning the Sultanate with the French Republic. This diplomatic reversal forced the overstretched Royal Navy to contend with the powerful Madjriti fleet, while Madjriti troops flooded into France to reinforce Republican armies fighting Royalist insurgents in Brittany.

Supported by their new allies, Republican forces launched a brutal counter-offensive in the west known as the "Bataille De Sang," steadily driving British and Royalist troops back toward the port of Brest. In March 1796, the anti-Republican coalition attempted a desperate breakout, initially routing the French lines with British artillery support. However, the operation ended in catastrophe when a Madjriti fleet unexpectedly intercepted the Royal Navy squadron guarding the port. In the ensuing naval engagement, the British fleet was decimated, losing eight ships of the line and its admiral. With their naval lifeline severed, the Royalist defense collapsed, and Brest fell to the Republicans in July, effectively ending the civil war in western France.

The stabilization of the military situation emboldened moderate elements within the French government to move against the radical leadership that had terrorized the nation. Recognizing that the Vanguard’s extremism would provoke perpetual rebellion, General Jean Aubry led a political purge in May 1796. By ousting Vanguard members from the Council and the People’s Assembly, the coup dismantled the faction's political power, bringing an end to their era of governance and signaling a shift toward a more stable, albeit still revolutionary, republican regime.
