The Battle of Mallorey, also known as the Massacre of Mallorey by the Ostians, was part of the early campaign conducted by the Kingdom of Vesryn during the Ostian War of Independence. After a successful incursion as far as Bellmare and Summershore, Lord-Lieutenant Austyn Preston was sent on the orders of Lance Captain Adair níc Chollaigh to bring the southern hamlets and towns under Vesryne control. Taking a small detachment, Preston led his men southwards for two months, reaving and plundering from hamlets on his way to the major village of Mallorey. There he met with resistance in the form of the local militia, reinforced by the local army garrison under the command of Ostian Captain Trystan Birchwood.
