After many years of bloody war Khan Tervel lead the Bulgarians to the walls of Moscow. All hardened veterans, who saw not one nor two deaths and destruction, they all was astonished by the fortifications of Moscow. The Russian capitol is built on high hill and river and sea surround its walls from all the sides, making it almost unassailable. Highly trained musket man were defending the capitol. And yet the Bulgars have not come to here to just turn around and return. In the blackest night, even not waiting for all the reinforcements and siege weapons to arrive, the Khan gave orders and the storm begun. The blood spilled and covered the slopes of the hill, many attacks were deflected and many soldiers have died, but at dawn Khan Tervel appeared from the smokes and the shouts of the attacking and dying men to lead the final storm himself and the last heavily wounded Russian defender fhit the ground. The city was taken. The citadel and the Russian Tzar palace was destroyed along with many buildings during the fierce fights. Only few of its citizens survived to kneel before the victorious Khan Tervel.
The Tzar himself is believed to be killed in the onslaught. He payed with his life rejecting so many times the Bulgarian supplications and plea for being friends and allies. This is how the mighty but stubborn and treacherous Russia have fallen.
