Garibaldines took part in the Greek-Turkish War, 1897 and fought especially at the battle of Domokos, where they were distinguished. One of our greatest national poets, Kostis Palamas, has devoted hymns to these Philellenes in some of his poems.
As you see in one of the pictures, as there was a good number of Italian volunteers and there was a shortage of uniforms, some volunteers are half-dressed in Garibaldian attire.
Maybe a source of inspiration?
