One of the most intriguing thigs about the Baltimore story is that the Corsair captain was actually Dutch. Actually there seems to have been a fair bit of cooperation in the 17th cebtury between pirates based in North Africa and in the Low Countries (notably Dunkirk) and in the Hebrides.

There were lots of other raids by Corsairs and others - in 1640 thirty people near Penzance were carried away by them - so there really were "Pirates of Penzance"

One song about a captive escaping from "Turkish" captivity is of course Lord Bateman, though he's not envisaged as having been captured by Corsairs.
