The Barbarian Invasions of the Roman Empire would be the best title for this map. For centuries invaders picked away at the Roman Empire, eventually contributing to its collapse. The lines and arrows represent some of these invaders: Orange= the Vandals, Green= the Huns, Yellow= the Visigoths, Blue= the Ostogoths, and Red= the Franks therefore it is A.
The turning point of the American Revolution occurred at the battle of "Saratoga," due mostly to the fact that the the colonial victory of Britain convinced the French to officially support the colonial army against the British.
