The first military engagements in Sri Lankan history were marked by the advent of Prince Vijaya, a prince from the Bengal region who landed along with his followers on the beaches of northwestern Sri Lanka around 543 BC. Prince Vijaya and his followers occupied the lands of the native Vedda people. Repeated incursions by South Indians, particularly the Cholas, into Sri Lankan territory occurred throughout the next few centuries and led to the engagement of the rival forces in battle. In one famous encounter, Sinhalese King Dutugamunu (161-37 BC) raised an army of eleven thousand in his battle against the Chola invader Elara, whom he eventually defeated. Dutugemunu's organisational skills, bravery and chivalry are famous and his battles have gone down in history as outstanding offensive operations.
