It had been decided that the riot would take place on 25th March 1844 to coincide with the anniversary of the War of Independence. However, the information transpired because of Makriyiannis’ enthusiasm. On the night of 2nd September some important members of the movement went to Makriyiannis’ house to give the final signal. The gendarmerie observed the strange movements outside the house and surrounded it. Kallergis, realizing the gravity of the situation, began the riot immediately. He sent his people to help Makriyiannis occupy the main buildings of authority and he went to the Palace along with 2000 soldiers. He was received with great acclaim by the citizens of Athens who hastened to join him. Otto sent his Ministers to negotiate but Kallergis arrested them at once. Otto, who was frightened, asked for the firearms, but his delegates aligned themselves with the rebels. The people and the army scattered at 3o’clock in the afternoon of the following day (3/9/1843), after having been informed that all their demands had been accepted.
