As with earlier revolutionary activity in Macedonia, the uprising of 1854 broke out on two fronts. The first was in southern Macedonia, where the Olympos chieftains (aided by fighters who had rushed there from free Greece and the rebellions in Thessaly and Magnesia) briefly captured Tempe and some parts of Pieria.
Meanwhile, the chieftain Theodoros Ziakas took the western Pindos, using it as a base from which to raid the Grevena area. However, under pressure from the large Ottoman army and the unpropitious diplomatic circumstances, a truce was negotiated by the consuls of Britain and France. Hostilities ceased in June 1854 and the rebel leaders returned to the Greek kingdom.
The second front of the uprising was Halkidiki. The actions of Tsamis Karatasos, who had landed in Sithonia in April 1854, were daring. But despite the widespread enthusiasm of the inhabitants, the monks of Mount Athos did not support the rebellion. Finally, succumbing to both diplomatic and military pressure (the arrival of English and French forces in Piraeus), the remaining rebels returned to southern Greece on board a French steamship, defusing thus the risk of a Turkish invasion of Mount Athos and its possible destruction.
