First day of the three-day Battle of Dervenakia, between the Ottoman Empire force led by Mahmud Dramali Pasha and the Greek Revolutionary force led by Theodoros Kolokotronis.

The Battle of Dervenakia was the Greek victory over the Ottoman forces on 6–8 August 1822, an important event in the Greek War of Independence.

The Ottoman Empire, also called the Turkish Empire, was an imperial realm that controlled much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe, between the early 16th and early 18th centuries.

Mahmud Dramali Pasha, was an Ottoman Turkish statesman and military leader, and a pasha, and served as governor (wali) of Larissa, Drama, and the Morea. In 1822, he was tasked with suppressing the Greek War of Independence, but was defeated at the Battle of Dervenakia and died shortly after.

The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. In 1826, the Greeks were assisted by the British Empire, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their vassals, especially by the Eyalet of Egypt. The war led to the formation of modern Greece, which would be expanded to its modern size in later years. The revolution is celebrated by Greeks around the world as independence day on 25 March.

Theodoros Kolokotronis was a Greek general and the pre-eminent leader of the Greek War of Independence (1821–1829) against the Ottoman Empire.
