While I continued my war with Hannibal, Monty made peace with DeGaulle and then attacked Sitting Bull. That goes poorly, and Sitting Bull takes Teotihuacan. DeGaulle would later resume the war against Monty. By the time I finally conquered Hannibal in 800, I was lagging badly in tech. Hannibal was the tech leader, with at least seven techs I didn't have. But I decided his death was more important that taking a tech that prolonged his life.
DeGaulle has captured Monty's two remaining continental cities (Monty had two left on the resource island), when I attacked DeGaulle. I captured Paris in 1300, but Monty would still decide to capitulate to DeGaulle in 1370, thus joining the war against me. Although his ships were a nuisance, he never tried to launch an assault to retake his homeland. Curiously, though, as I captured the rest of France, Monty never broke free from DeGaulle. Before I took DeGaulle's last city (Monty's old capital of Tenochtitlan) in 1470, Monty was up to 160% of his master's land and 227% of his pop!
I don't have enough galleys for a serious naval invasion, yet, so I attack Sitting Bull in 1520 and then make peace with Monty for a tech. Sitting Bull turns out to have enough crossbows to hold off my maces, so it takes some time for me to build muskets and push forward my attack. The Native American Empire is conquered in 1700.
I attack Monty again, but some border pops bring me just over the edge of the Domination victory limit in 1735, before I can take his remaining two cities. Pacal, who had settled most of the resource island before I even know where it was, had remained pleased with everyone for the entire game, and entirely pacifistic.
