The Fall of Siberia marked the beginning of the end for Russia’s instability. After it, only two more battles were fought, and compromises were finally reached between rival combatants. It seemed like Yegorov’s plans had succeeded beyond even his expectations.
The Rus League was the first to fall, and that required no battles at all. It fell not with a bang, but with a whimper, as it was mostly held together by the leadership of Prince Oleg of Kiev. This man quickly realized that the end of the Russo-Swedish War and the Fall of Siberia meant the end of the Russian Coalition, so he attempted a desperate rallying of the entire Rus League. Unfortunately, it seemed that only he felt threatened by the twin Tsars, and he received no support for a counterattack.
Left adrift, he determined to launch one final doomed attack upon Moscow. “Our cause has no defenders and is lost,” he is alleged to have said. “I can at least let it die with some dignity - and some glory”.
His attack on Moscow was predictably a failure, and it can’t even be called a battle. He attacked Tsar Alexander II’s forces with barely more than 2000 men - hardly a force that could be called an army. Still, he had the element of surprise. He managed to inflict a few casualties before he launched his true last hurrah. He charged Tsar Alexander II, who honorably met him in a duel. They crossed bayonets, but the Tsar was far stronger than the rebel Prince of Kiev. Still, Prince Oleg fought with all his might and managed to hold back his foe for a full day, allowing his army to flee - or to surrender. By November 1858, though, Prince Oleg lay dead upon Moscow’s streets. His dream of Russia as a loose confederation died with him.
The Siberian portions of the Rus League defected to Tsar Konstantin, while most of the League west of the Urals swore allegiance to Tsar Alexander, who took Kiev in January 1849.
Further good news arrived in Moscow that month. An assassin had managed to put down the Mad Tsar - it was later discovered that Yegorov sent this assassin. Everything was down to the two Tsars, and their battles would be legendary. Many men like Yegorov stayed neutral - all they cared for was that Russia was united, not who it was united under.
The first clash occurred in April in Pyatigorsk in the northern Caucasus. It was an attack by Tsar Alexander II upon his brother, as he sought to force Konstantin into a battle on his terms. This plan succeeded perfectly. Pyatigorsk was famed for its mineral springs, and it was these that Konstantin fought to defend.
Tsar Konstantin and Tsar Alexander II never directly dueled again at Pyatigorsk, but their armies fought like legends. Men were reported to have fought underwater and from atop buildings. They desperately fought for their rightful rulers. In the end, Tsar Konstantin retreated from the city, but he promised his men that they would return to the spa city victorious to vacation like victors - and he would keep his promise.
The two armies would meet again in September - at Adygea. Here, Tsar Alexander II and Tsar Konstantin had their long-awaited rematch, and their armies fought like demons. Both armies climbed the Chugush Mountain and fought each other throughout in a struggle that took a month - and that proved to be nothing more than a prelude. Ultimately, they would extend their conflict throughout the entire oblast, fighting across many rivers.
It was at the height of Chugush that Tsar Konstantin finally began his rematch with his brother. He was still blind, but he had learned how to fight in spite of this - many martial arts were still useful to the blind, and there were many organizations that taught the blind to fight. Konstantin had learned from these as much as he could before the Russo-Swedish War began, and he didn’t let that war slow down his progress.
Even in spite of this, though, the duel began with Tsar Alexander II disarming his brother, and he then proceeded to threaten his life with both of his guns. However, this was just what Konstantin wanted - he used some of his newfound skills to disarm his brother of both of his weapons, but he was unable to catch them, so the duel devolved into a fistfight. Even the outbreak of night was unable to stop their duel, as the stars watched them clash. They would stay awake and fight for nine days until, finally, they had reached the ground and were too tired to go on.
From there, they both rested alongside their armies, and Konstantin grabbed a sword. Tsar Alexander II grabbed another gun. They then dueled, sword against gun, for a further three days, until they had lured each other to the banks of the Kuban River. There, Konstantin disarmed his brother once more, and he used his sword to force him to back up… which he did.
Unfortunately, he wasn’t looking behind him as he backed up, and Tsar Alexander II quickly fell into the Kuban River. Tsar Konstantin was horrified by this, and he even dived in after his brother, but it was for naught - Tsar Alexander II had already drowned.
After this, the Blind Tsar is said to have proclaimed, “Oh, God! Why did my brothers and I have to rebel against my righteous brother? Why did we hate each other so? Is this what ambition has wrought?”.
Regardless, the battle was over. Tsar Alexander II’s army surrendered and didn’t fight for his successor. Tsar Konstantin inherited his lands, and Russia was reunited at last… at a terrible cost. The Russian Age of Chaos killed thousands for such a petty reason. It served as a warning to Russians of the dangerous divisive potential of ambition…
