Revolutionary Dimitar Stefanov-Kazaka

Dimitar Stefanov, called "the Cossack", was a Bulgarian fighter for Bulgaria's liberation and the second standard-bearer in Hristo Botev's detachment. He was the son of Stefan Ivanov from Yambol and came from a family that participated substantially in the Russo-Turkish War of 1828–1830; he had four brothers and one sister.

After his brother Ivan was hanged in Adrianople, the brothers Vasil and Dimitar joined the detachment of Hadzhi Dimitar and Stefan Karadzha in the Sliven Balkan Mountains in 1868. They subsequently left for Russia. In 1876, Dimitar Stefanov joined Hristo Botev's detachment and became its second standard-bearer after Nikola Simov-Kuruto's death at the Battle of Milin Kamak.

Dimitar Stefanov flew Botev's detachment's flag in a series of battles, including in Rashov Dol valley and through the Cherepish Rocks. In June 1876 he took refuge at Cherepish Monastery, where he was hidden by Geko Palev, the revolutionary Geko Pavlov. Subsequently, after betrayal by local villagers, he was captured by the Turkish authorities.

Dimitar Stefanov, known as "the Cossack", suffered brutal torture and was beheaded by Malich Agha, who ordered his body burned. Before this, he was subjected to severe physical torture, including the cutting of his ears and breaking of his fingers. His body was buried at the Cossack's death site near Kremikovtsi Monastery, where a monument was later erected in his honour.
