  In late August, elections were held for the National Convention. New restrictions on the franchise meant the number of votes cast fell to 3.3 million, versus 4 million in 1791, while intimidation was widespread. The Brissotins now split between moderate Girondins led by Brissot, and radical Montagnards, headed by Robespierre, Georges Danton and Jean-Paul Marat. While loyalties constantly shifted, voting patterns suggest roughly 160 of the 749 deputies can generally be categorised as Girondists, with another 200 Montagnards. The remainder were part of a centrist faction known as La Plaine, headed by Bertrand Barère, Pierre Joseph Cambon and Lazare Carnot.
  
  In the September Massacres, between 1,100 and 1,600 prisoners held in Parisian jails were summarily executed, the vast majority being common criminals. A response to the capture of Longwy and Verdun by Prussia, the perpetrators were largely National Guard members and fédérés on their way to the front. While responsibility is still disputed, even moderates expressed sympathy for the action, which soon spread to the provinces. One suggestion is that the killings stemmed from concern over growing lawlessness, rather than political ideology.
  
  On 20 September, the French defeated the Prussians at the Battle of Valmy, in what was the first major victory by the army of France during the Revolutionary Wars. Emboldened by this, on 22 September the Convention replaced the monarchy with the French First Republic (1792–1804) and introduced a new calendar, with 1792 becoming "Year One". The next few months were taken up with the trial of Citoyen Louis Capet, formerly Louis XVI. While evenly divided on the question of his guilt, members of the convention were increasingly influenced by radicals based within the Jacobin clubs and Paris Commune. The Brunswick Manifesto made it easy to portray Louis as a threat to the Revolution, especially when extracts from his personal correspondence showed him conspiring with Royalist exiles.
  
  On 17 January 1793, Louis was sentenced to death for "conspiracy against public liberty and general safety". 361 deputies were in favour, 288 against, while another 72 voted to execute him, subject to delaying conditions. The sentence was carried out on 21 January on the Place de la Révolution, now the Place de la Concorde. Conservatives across Europe now called for the destruction of revolutionary France, and in February the Convention responded by declaring war on Britain and the Dutch Republic. Together with Austria and Prussia, these two countries were later joined by Spain, Portugal, Naples, and Tuscany in the War of the First Coalition (1792–1797).
