Born in Macedonia, Ottoman Empire in 1906, Dimitrios Itsios was a Greek Vlach reserve non-commissioned officer (Sergeant) in the Greek Army during World War II. In April 1941, he was ordered, as head of five soldiers, to defend and maintain the P8 Pillbox in the Omorfoplagia area of Mount Beles near Ano Poroia Serres. Despite ordering all of his men to escape, two stayed with him and they fought until their ammunition was exhausted, causing great losses and killing approximately 230 enemy German soldiers. When the three Greek soldiers surrendered, Itsios, after saying that he had simply done his duty, was assassinated by the German Lieutenant General Sorner. According to the testimony of the two Greek soldiers who were released, Sorner was angry for the loss of so many of his men.
