No save file. I kept overwriting saves whenever I managed to capture a Castle =). Even if you somehow manage to break through with a thousand-unit army, problem number 2 will arise – what to do with the blue player who has been developing and accumulating troops all this time. When I tried to build up my army, it turned out that when I landed on the island, the blue player showed up right then. So, even if I had killed the pirates, I wouldn't have been able to defeat the blue player with his ogre mages =). Added: http://webfile.ru/5730651 - link to an archive with save files, I made a test base for you =)
rezerv - save after the first battle (decided to capture the second centaur dwelling), the battle was quite successful, I lost 16 berserkers and killed 45 centaurs.
Month № / Year 1 - saves at various stages of army building.
BlueArrive - the blue player showed up, he already had 250 ogre mages, but for some reason, he didn't attack me. Moreover, he captured the nomad dwelling, but I noticed this a little late. You can try loading this save and immediately take the nomad dwelling. =)
Battle 1 / Battle 2 - battle for the shipyard and the war chariot (during the first battle, I lost many berserkers, but I wasn't too worried, as I don't think this will work). Good luck =)
