The American War of Independence Edition contains 23 historical scenarios for Master and Commander. The scenarios simulate naval battles from the American War of Independence and include 12 Small (1-2 ships per side) battles 5 Medium (up to 10 ships) battles 6 Large (Fleet) battles From the back of the book: Many of these scenarios show the French doing a lot to keep the British Royal Navy busy rather than intervening directly on land in the 13 colonies. This hampered British strategic mobility and eventually led to the surrender at Yorktown (compared to the easy evacuation of Boston), as well as the threat of losing more Caribbean colonies making the war too costly for the British.
