Greek War of Independence: At the Battle of Gravia Inn, a 120-man Greek force led by Odysseas Androutsos repulsed an Ottoman army of 8,000 soldiers.

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.

The Battle of Gravia Inn was fought between Greek revolutionaries and the Ottoman Empire during the Greek War of Independence. The Greek leaders Odysseas Androutsos, Yannis Gouras and Angelis Govios, with a group of c. 120 men, repulsed an Ottoman army numbering 8,000 to 9,000 men and artillery under the command of Omer Vrioni and Köse Mehmed. The battle ended with heavy losses for the Ottomans and minimal casualties on the Greek side.

Odysseas Androutsos was a Greek armatolos in eastern continental Greece and a prominent figure of 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.
