Its just that the last 10 turns took like 6.5 hours. Moving those Infantries tile by tile towards the enemy cities can be a pain. 
Knowing that once each stack reach their destination the city will sure fall does help some.
And the Egyptian SoDs that can't make up their mind which city to take can be a pain. Of course, with the thin rail line in the New World, it really doesn't matter which city the AI choose, a stack of 10-15 infantry can be in the city before any attack. 

Knowing that once each stack reach their destination the city will sure fall does help some.
