On this day, 165 years ago, on May 11, 1860 (March 21, the 1860 lunar calendar), the famous "Thousand Army" in world history began its expedition. In April 1860, a people's uprising broke out in Palermo, the capital of Sicily, and was brutally suppressed by the Sicilian army. At the suggestion of the Republican Party led by Mazzini, the Italian national hero Garibaldi decided to sail on an expedition to Sicily to help the rebels, but King Sardinia did not agree to give him a single soldier. So he recruited more than 1000 volunteers and began the "Thousands of Soldiers" expedition on the night of May 5. Two ships left the coast of Genoa carrying 1400 soldiers. They formed seven companies. In order to cover up the real goal of the expedition, Garibaldi sent a small force to feint the Pope States. The main force entered the port of Masala at the westernmost point of Sicily on May 11, landed successfully, and began to march towards Palermo. On May 15, he led his troops over mountains and mountains to advance north to Karatafimi. There are three enemy battalions of more than 3000 people in Jiagu leading to the city, equipped with cavalry and artillery. Garibaldi, with more than 1000 people, occupied the enemy position in one go, drove straight into the city of Palermo. The enemy had more than 22,000 troops in Palermo, far exceeding Garibaldi's main force. Starting from the 20th, Garibaldi attacked the southwest of the city, enticing enemy generals to send troops from the city to the southwest suburbs. By the 24th, more than 10,000 enemy troops had arrived outside the southwest city. Garibaldi fought and marched, pretended to retreat, and lured the enemy troops to pursue, reducing the number of enemy troops in the city to more than half. At this time, Garibaldi suddenly changed the direction of action and unexpectedly transferred his main force to the Michiermeri Valley near Palermo. In the early morning of the 27th, all residents of Palermo took up arms. With the cooperation of the residents, Garibaldi stormed the port of Termini in the southeast of the city and liberated Palermo. It took less than 20 days from the landing of Masala to the liberation of Palermo. Garibaldi defeated a well-equipped superior enemy with inferior troops with poor weapons, which fully demonstrated Garibaldi's military talent. Marx praised him as "not only a brave leader and outstanding strategist, but also a resourceful commander." Inspired by the victory of Garibaldi's "Army of Thousands", the flames of uprising immediately burned all over Sicily, promoting and accelerating the cause of Italy's unity and independence. The "Thousands of Army" has written a glorious side in Italian history.
