Siege of Worcester (Anarchy) was a medieval siege, the investment of a fortified position, fought at Worcestershire, England in 1139. Miles of Gloucester (Angevin/Empress Matilda's faction, based at Gloucester) prevailed over Worcester's citizens and garrison, loyal to Waleran of Meulan (Royalist, Earl of Worcester). Attackers breached the city's northern side, burnt part of Worcester, and took plunder and prisoners for ransom; the greater part of the city survived unburnt. Waleran of Meulan retaliated on 30 November by attacking Sudeley Castle.
The site of Siege of Worcester (Anarchy) lies on Triassic Rocks (Undifferentiated), bedrock that formed in the Triassic. The rock here is mudstone, siltstone and sandstone.
