With the exception of the area around Mount Olympos, where the armed chieftains had a long experience in staging uprisings, western Macedonia did not possess the manpower and essential supplies that would have guaranteed a successful revolution.
The efforts of Nikolaos Kasomoulis, the local leader and a member of the 'Philiki Etaireia', to find help in southern Greece were of little consequence. The armatoles of Olympos, with no organization whatsoever, along with a token force which had finally arrived from southern Greece, fought for a mere few weeks (from late March to early April 1822).
Shortly afterwards, they joined up with the Greek revolutionaries who had already mounted an uprising in Naousa, having taken up battle positions on 19 February. Despite the town's reserves of arms and ammunition and despite the efforts of the Naousan notable Zafyrakis Theodosiou and the kapetans Tasos Karatasos and Angelis Gatsos, Naousa was captured on 13 April by Mehmed Emin Pasha. Two thousand Christians were slaughtered, while most of the surviving rebel leaders left to continue the fight in southern Greece.
