context_page_description: The Battle of Petra was the final battle fought in the Greek War of Independence.
context_section_description: In order to follow his orders to march into Thrace, Osman Aga signed a truce the following day with the Greeks. According to the truce, the Ottomans would surrender all lands from Livadeia to the Spercheios River in exchange for safe passage out of Central Greece. This battle was significant as it was the first time the Greeks had fought victoriously as a regular army. It also marked the first time that Ottoman Empire and Greeks had negotiated on the field of battle. The battle of Petra was the last of the Greek War of Independence. Demetrios Ypsilantis ended the war started by his brother, Alexandros Ypsilantis, when he crossed the Pruth River eight and a half years earlier. As George Finlay stresses:
  "Thus Prince Demetrios Ypsilantis had the honour of terminating the war which his brother had commenced on the banks of the Pruth."
