Siege of Castrum Tiberium
The Siege of Castrum Tiberium was the culmination of the Long March, the initial campaign by Tariq Kimepra against Imperial Kamalbia. A major episode of the War of the Magpie and the Dragon, it saw seven thousand men under Kimepra besiege the fortress of Castrum Tiberum, the centre of the military and colonial administration in the province. Outnumbered more than three to one, the Exponential garrison under Tiberius Amantius held out for six months in hopes of a relief force while Cadenzan ships maintained a blockade of the city's harbour. Amantius surrendered the city in late April and was permitted to leave with his army; he returned a week later with Kamalbian allies in an attempt to retake the city at the Battle of Ialica.
