перевидите плиз All Russian people know the names Alexander Suvorov an
d Michael Kutuzov. They are two famous generals. Alexander Vasilyevich Suvorov was born in 1729. He was a noble, honest man, devoted to his country and his people. Suvorov took part in many wars. He had a lot of victories because he knew army life very well. Suvorov had a kind heart. He loved his soldiers, and they loved him. His soldiers were never hungry, and his officers took care of the soldiers, though their life was not easy at all. Suvorov taught his soldiers and officers to be brave; he taught them to win in the battles against the enemy. Michael Kutuzov was Suvorov's pupil. He was born in 1745 in St Petersburg. His father was an engineer in the Russian army. Little Michael was an excellent pupil. He was good at maths and knew many foreign languages. When he became an officer, he took part in many battles. He was a brave and honest officer. Kutuzov believed in Russian soldiers. He taught them the art of winning. When Kutuzov was forty-five years old, he became a general. During the war of 1812 Kutuzov was an old man, but he won some important battles. After the battle of Borodino it took Kutuzov only three months to win the war completely. Napoleon ran away from Russia. Russia again became free and independent..
