In spite of his victories he was again deposed in February 1595, shortly after the accession of Mehmed III, and banished to Malkara. In August, Sinan was in power again, called on to lead the expedition against Prince Michael the Brave of Wallachia. His defeat in the Battle of Călugăreni, the Battle of Giurgiu, and the series of unsuccessful confrontations with the Habsburgs (culminating in the devastating siege and fall of Ottoman-held Esztergom), brought him once more into disfavour, and he was deprived of the seal of office (19 November).
