John Ashby (Royal Navy officer)

John Ashby (c. 1640 – 12 July 1693) was an English admiral in the Royal Navy during the late 17th century. He served with distinction during the Nine Years' War, particularly at the Battle of Bantry Bay in 1689 and the Battle of Beachy Head in 1690.

Ashby entered naval service early in life and rose through the ranks. He was appointed a captain in 1666. His career advanced significantly during the reign of William III. At Bantry Bay, serving as a rear admiral, he commanded the Blue Squadron and played a crucial role in the engagement against the French fleet. While the battle was indecisive, Ashby was knighted for his bravery and leadership.

At Beachy Head, Ashby, by then a vice-admiral commanding the Blue Squadron, faced criticism for his perceived slowness in engaging the French fleet. Accusations of cowardice and disobedience were levied against him, despite his assertions that the prevailing winds and the French fleet's maneuvering made closer engagement impossible. He was cleared of wrongdoing at a court-martial, but the controversy surrounding his conduct persisted.

Following Beachy Head, Ashby continued to serve in the Royal Navy. He was promoted to Admiral of the Blue in 1693, shortly before his death in Portsmouth. His career, marked by both valor and controversy, reflects the complex political and naval landscape of the late Stuart period.
