Location
Cause → Event → Consequence
Following decisive Neapolitan defeats at the Battle of Tolentino and the Battle of San Germano, King Joachim Murat fled to Corsica. Command of the Neapolitan army passed to General Michele Carascosa, who sought peace with the advancing Austrian and British forces.
On 20 May 1815, Pietro Colletta, Adam Albert von Neipperg, and Lord Burghersh signed the Treaty of Casalanza at the Lanza family villa in what is now Pastorano, Campania, formally ending the Neapolitan War between the Napoleonic Kingdom of Naples and the allied Austrian Empire and Great Britain.
The treaty restored the pre-Napoleonic King Ferdinand IV of Naples and Sicily to the Neapolitan throne under relatively lenient terms: Neapolitan generals retained their ranks and the kingdom's borders remained unchanged. Blockaded garrisons at Ancona, Pescara, and Gaeta subsequently surrendered, with Gaeta holding out until August 1815.
Political Outcome
Restoration of Ferdinand IV to the Neapolitan throne; lenient armistice terms for Neapolitan forces including retention of ranks and unchanged borders
Napoleonic Kingdom of Naples under Joachim Murat
Restored Bourbon Kingdom of Naples under Ferdinand IV
