June 1, 1849, outskirts near the capital Rome of the Pope State/Roman Republic.
The outskirts of Rome, shrouded in overnight heavy rain, exuded a stench of decay and mildew.
This was the fourteenth day since Rome was besieged. Since May 17, when the "bandit army" of the French Republic (a derogatory term by the Roman Republic Volunteer Army for the French Republic) occupied the rural areas around Rome, the war had been centered around the outskirts of Rome.
With over 14,000 French soldiers under his command, the Commander-in-Chief of the Roman Expeditionary Army, General Renio, methodically planned, relying on the powerful navy transport capability to move nearly 20 heavy cannons, while feigning sincerity in writing secretly to Mazzini, claiming that he had come to Rome to protect the Roman Republic.
The executive authorities of the Roman Republic, led by Mazzini, naturally did not wish to believe Renio's words.
