Naval operations under Cromwell

What naval operations occurred under Cromwell?

The Commonwealth deployed powerful fleets under generals-at-sea such as Blake, Monck, Penn, and Montagu, fighting major battles and extending English power overseas.

Robert Blake, Richard Deane, Edward Popham, George Monck, William Penn, and Edward Montagu were among the Commonwealth's generals-at-sea. That terminology describes a command system that does not map neatly onto the later familiar sequence of admiral ranks. Monck and Montagu are singled out as especially successful, with major battles and overseas expansion including Jamaica. The answer provides a concise route into the navy between civil war and Restoration and identifies the commanders worth following into a deeper study.
