The Siege of Tiber was a key battle between the United Empire of Earth (UEE) and the invading Vanduul that took place in the Tiber System. Lasting from 2732 to 2736, it consisted of prolonged ground and air engagements, mass bombings, and a military blockade from the Orion and Viking jump points by Vanduul forces and the Virgil and Oberon jump points by UEE forces. Losses were heavy on either side; conservative estimates put Human and Vanduul combined casualties in the lower millions. The Siege ended with UEE defeat on 29 December 2736, when a Vanduul Kingship jumped into the system from Orion. Half of the UEE’s forces were destroyed in the subsequent battle. After such heavy losses, the UEE was forced to cede Tiber to the Vanduul.
"This is our time. The line has been drawn and for the first time, our enemy will feel our resolve in every battle. When they push, we will push back. They will learn that Humanity has stopped running."
Grand Admiral Tesca Halimeade, Commanding Officer of UEE Naval forces in Tiber, 2735 (killed in action)
