In 1901, I offered an alliance to England to fight France. He agreed, and so we both sent a message to France offering a WT with the intention of immediately going back on it and attacking him. France agreed, although he tried to get me on board for a Sealion.
In the fall of 1901, England and I were discussing what to do with Belgium and France. We both wanted to deny France the extra build conferred by Belgium but I also wanted to carry on the attack. I bounced France out of Belgium and told England to convoy an army to Brest (France had told me he was not going to cover Brest with his fleet). England, however, moved his fleet into Brest (and simultaneously botched a move order for his army). This aroused my suspicions because (1) no one actually screws up orders like that and (2) this was the setup for a Hey Bresto. England assured me that it was merely a mistake, and France was sending me messages to indicate how his displeasure at England, so I thought little of it.
I was hoping that an English army in Brest would allow us to push deeper into France and give me the chance to make up for limiting myself only to one build in 1901, but this proved to be a mistake. The English fleet in Brest did little to help, and from what I've read above, I was right in guessing it was a Hey Bresto.
In spring 1902, I was talking with Russia about how I would not help England into Sweden if in exchange he stayed out of Bohemia. I wanted to make sure that Austria didn't go under because he was the only person I figured I could maintain an alliance with. I told England that I would support him into Sweden in the fall because I wanted to give Russia at least something to trust me on, but we had an argument about this. England eventually convinced me to help him take Sweden in the spring. It turned out that Russia moved to Bohemia anyway, so I guess it didn't matter too much that I'd helped England take Sweden.
While this was going on, I was also talking to Italy. Austria had passed on some information that Italy was gunning for Munich, so I tried to confront him about this. Naturally, he denied it, and from what I was able to gather from others was that Italy was telling something slightly different to everyone. I bounced him out of Tyrolia anyway because I absolutely did not want him near Munich and I was also concerned that he would help Russia take Austrian centres.
In fall 1902, England, France, and Russia all conspired to attack me. I lost Denmark and Munich, but gained Holland. I was promised Belgium, but England took it instead. I had tipped my hand to England immediately prior because I figured that since I had helped him take Sweden he wouldn't be in search of additional supply centres and I also hoped that he hadn't solidified an alliance with France.
Following that phase, I offered support to each of the three countries against another, citing vengeance as my motivation. France and Russia both agreed they would like my help against England, so I made plans to attack England. I told Russia to take Denmark in the spring so that he could hopefully move on the North Sea in the fall, but somehow our communications got crossed and he tried to support me into Denmark. He told me he had simply erred in entering his orders, but after I had already swallowed that line from England, I wasn't having it this time. I took English support into Sweden (because he had agreed to attack Russia with me), but then he took Holland.
After that, I took back Denmark in the spring, but there were English units all over me, and I knew it would be an essentially futile exercise to survive for much longer. I spoke to France about taking back Munich, but I generally stopped trusting his word too. After I lost Kiel, I figured I might be able to help anyone against England, so I just did what France told me to do while waiting for elimination.
