Murad's force contained approximately 80,000 men and two cannons, which could fire 200 pounds (91 kg) balls.[4] His army contained a fresh corps of Janissaries, and 3,000 debtors and bankrupts fighting to regain their freedom. The Count of Gurrica persuaded Skanderbeg to incorporate a scorched earth strategy, by destroying all supplies that might be used by the Ottoman army.[15] The Ottoman force paraded around the fortress and offered 300,000 aspras (Turkish currency) to those who would open the gate and let the Ottoman army in the fortress without a fight.
