In a recent game as the Babylonians, I had just finished fighting a war against the Koreans to the north when the Mongols to the east decided to get aggressive and launch an invasion.
Luckily, the fools decided to invade with a force of medieval infantry and archers, through a patch of forested terrain. I had two cities just the other side of the forest, and by adjusting the size of the two garrisons I kept the mongol army heading first for one and then the other (marching through the forest as they went) as they tried to attack the one that their 'intelligence reports' said was the most lightly defended.
In the meantime, my horsemen, ancient cavalry (gotta love that statue of Zeus) and Babylonian Bowmen were able to launch attacks against the Mongol hordes from either city (once they'd arrived from the Korean front), or from the road that ran through the plains to the west, and whittle them down to the point where they gave up, sued for peace, and went home...
...which was nice.
