So Im playing an Epic length game on Prince as the French. I was all alone up in my area with my entire southern boarder lined with 5 city states making a nice barrier between me, the USA and the Aztecs.
Ive been chugging along, pumping out wonders and just doing my cultural thing and had developed a very friendly relationsihip with the USA, completed 3 research agreements, long lasting open boarders, cooperation agreements and secret pacts against Montezuma.
Then all of a sudden the US starts attacking the city state, Vienna, thats on the land bridge between us. I try and give Vienna unit support to keep the buffer between us but the US was the biggest military power around and eventually Vienna fell, and being right on my boarder Washington felt that was too much of a threat and promptly declared war on me despite our 3 thousand year peace and prosperity together. I thankfully was able to set up some key units and block his advance and finally put up an offensive of my own and retook Vienna.
At that same time I had just unlocked gunpowder and built around 3 Musketeers though none of them had been in battle yet. So after Vienna was retaken I though it was a decent time to see if Washington would settle for peace. He did but when I hit the "What Will Make This Work" button not only does he offer up all his luxuries and gold but he also give mes 5 cities, every city of his save for the Capital. What the hell just happened? I had at best 7 units three of which were Musketeers.
