أسوار القسطنطينية
In early December 1354, Francesco led a fleet to Constantinople. They approached the city late at night and pretended that they were in need of assistance. They claimed that one of their ships was sinking and requested help in salvaging the cargo from shipwreck, and promised a share of it to the sentries of the city for their help. Seeing a chance to profit, the sentries opened a gate. Francesco then led about five hundred armed men through the gate, took command of the Walls of Constantinople and roused the citizens from their sleep with shouts in favor of John V. Riots in favor of John V soon started. By 4 December 1354, John VI resigned his title and retired to a monastery.
