On 22 April 1453, Mehmed sent another expedition to Albania under Ibrahim Pasha. The same day, despite the storms, Skanderbeg launched a swift cavalry attack which broke into the enemy camp causing disorder and chaos. Ibrahim was killed in action along with 3,000 of his men. Skanderbeg's army continued looting before returning to Debar. He returned triumphantly with his army with whom he had split his booty. Five weeks later Mehmed II captured Constantinople, which deeply troubled the Christian states of Europe. Mehmed, by then called "the Conqueror", turned his attention to finally defeating the Kingdom of Hungary and crossing into Italy.
