Which British Admiral has a monument on the Breidden Hills?

George Brydges Rodney, 1st Baron Rodney, KB (bap. 13 February 1718 — 24 May 1792) was a British naval officer. He is best known for his commands in the American War of Independence, particularly his victory over the French at the Battle of the Saintes in 1782. It is often claimed that he was the commander to have pioneered the tactic of "breaking the line" used later by Nelson.

Rodney’s Pillar at the top of the hill was built by the gentlemen of Montgomeryshire who supplied oak from the area & shipped them down the river Severn to Bristol where Admiral Rodney’s fleet was built.
