Siege of Viborg (1710)
The siege of Viborg took place in the spring of 1710 during the Great Northern War (1700–1721), as a second attempt by the Russians to capture the fortress port of Viborg (today Vyborg), near the modern border between Russia and Finland, after a failed attempt in 1706. After the outbreak of the war, Swedish forces had fortified themselves in the port of Viborg.
