As the English Navy was expanding towards the end of the thirteenth century, new appointments of admirals with specific geographic responsibilities were created, Sir John de Botetourt was appointed "Admiral of the North" in 1294 this command lasted until 1412. Also in the same year the king appointed Sir William de Laybourne the dual commands of "Admiral of the South", (1294-1412) and "Admiral of the West", (1294-1412). In 1364 the post of "Admiral of the North and West" was created until 1414. Beginning in 1408 these admirals responsibilities were gradually absorbed by the office of the High Admiral of England, Ireland and Aquitaine (later Lord Admiral of England) leading to a centralized command the process ended in 1414.
