In my last game as the Japanese, a gigantic war spurred by intertwining MPP's broke out at the beginning of the industrial age. Soon everybody had infantry, but the best offensive unit was still the cavalry. The AI was having a hell of a time taken any cities because of the large differential between the infantry's 10 defence, and the cavalry's 6 offense. However, I had a lot (about 12) artillery. These followed my cavalry around protected by a couple veteren infantry units. I would park my invasion force one square inside the Persians borders which was within 2 squares of the closest Persian city. On the next turn, my artillery would reduce the population of the city to below 7 and damage all of the defenders down to 1 hp. Then my cavalry would charge, and after losing one or two (since they don't retreat if the defender is at one hp), I would take the city. My artillery and infantry would continue to advance, getting within range of the next city, and would begin bombardment again. After a couple of turns of this, the city is reduced smoldering ruins with a couple badly damaged defenders, and my cavalry were healed and reader to charge. I took over the entire sizeable Persian empire this way, and they could do nothing about it. I thoroughly enjoyed myself, and this reinforced my already healthy respect for artillery.
