During peace times, they kept the weaponry in arsenals named "cephane". The Djebedji unit participated in all campaigns commanded by the sultan or the grand vizier. In other campaigns only a part of the unit participated. Abolishment. In most Istanbul revolts during the stagnation and decline periods of the Ottoman Empire, the Djebedji units acted together with the Jannisary, and in 1826, when the Jannisary was abolished by Sultan Mahmud II following the Auspicious Incident, Djebedji units were also abolished.
