Europe against France
Throughout 1792, the new French Republic becomes increasingly radical, imprisoning members of the clergy along with nobles and confiscating their lands. Meanwhile, in New France, King Louis XVI has established his court in Québec. Thousands of refugees have been arriving, pouring into Québec, Montréal and New Orleans. Among these, is the majority of France's military and naval officers, nobility, and high clergy. Fortunately, grain prices have increased, along with those of cod allowing the new government some revenue, in addition the king soon grants large tracts of land to nobles, giving them the opportunity to earn some income.
In addition, in August 1792, Portugal grants King Louis XVI a subsidy of 13 million livres, allowing him to maintain his navy and rebuild in army in North America. This is soon followed by a loan from the United Provinces and a subsidy from Great Britain amounting to £1.3 million, in exchange for the opening of French ports to British trade. In the meantime, the British Navy and armed forces begin rearming heavily, this provides an economic boom not only for the British Isles, but for British America as well.
In contrast, the situation in France itself borders on one of famine as food supplies are low and the government has resorted to printing paper money, creating hyperinflation. The radical government accuses the foreign powers of aiding the king and imposing a blockade on France. Austria and Aragon are their first two targets as both are ruled by Queen Marie Antoinette's nephews. Barcelona especially has become a large gathering place for émigrés plotting against the French Republic. Perhaps to distract the populace from its internal problems, the French Republic declares war on Austria and Aragon in July 1792. This leads to Prussia joining the war against the French as the Prussians hope to gain territory at the expense of France.
Initially the war goes badly for the French Republic, as most of their officers have now emigrated and their corps are disorganized. A joint Austro-Prussian force invades France in July 1792, capturing most of Flanders and by October having reached the outskirts of Paris. However, this foreign invasion leads to a uniting of the French and a "levée en masse" with over 200,000 men going to defend the city. They manage to push back the German invaders, giving the new republic a much needed morale boost.
The Prussians and Austrians now facing a guerrilla campaign decide to withdraw their men rather than face the risk of losing their armies. Meanwhile, the House of Savoy declared war on the France, invading the southern portion of the country in an attempt to recapture Toulon. However, with most of their forces tied down in North Africa, the French are able to driving them out, occupying Nice and Savoy. Further north, the French armies have not only reconquered Flanders, but have occupied most of the German lands west of the Rhine River.
In northwestern France however, and especially in Brittany a mass uprising against the republic began in September 1792 after laws were promulgated against priests who would not swear an oath to the Republic. This leads the British to send 25 ships of the line to the Channel Islands with 6,000 troops to observe the situation. These actions, along with British assistance to the royalist government in Quebec lead to a declaration of war by France in January 1793. This is followed by declarations of war against Portugal and the United Provinces in February and finally, Spain in March 1793.
In March 1793, the British occupy the French naval base at Brest, capturing what remains of the French Atlantic Fleet. This is followed by the capture of La Rochelle in May 1793 where the insurrection against the French Republic is at its strongest. The British for their part are joined by the French Royal Navy from Québec and a force of 6,000 Canadien soldiers. Brittany, Poitou and Normandy are now largely in Royalist control, forcing the government in Paris to dispatch 45,000 troops to the region.
In the Mediterranean, the French ruled Greek islands, though originally sympathetic to the revolution, turned against the anti-clerical laws. With the French Republican Navy unable to reinforce the garrisons there, they quickly surrender to the Russian Naval forces in June and July 1793. This leads to a declaration of war on Russia by the French Republic in July 1793. Even more serious is a rebellion at Toulon where the city is captured by British and Royalist forces in August of 1793.
Further south, the Portuguese Navy assists the French Royal Navy in retaking Alexandria. There the besieged French garrisons declare their oath of allegiance to King Louis XVI. However, French control of the region is largely confined to a few small cities, as much of the Nile Valley is in open rebellion against French Rule. In Syria too, the French Royalists are unable to establish control yet, as Syrian Christians have declared their loyalty to the French Republic.
