Igor resolved to find a cure for this failure, and set out for Tsargrad in 944, three years later. He went by sea, with a numerous army collected from all tribes between Lake Ladoga and the Euxine, including even Petchenegs of the southern steppe land. The Greek Emperor sent envoys to Igor, and as he sailed near the coast they met him north of the Danube, where they delivered rich presents. “Go no farther,” said they to him. “Take the same that Oleg took, even more will be given thee.” Advised by his attendants, Igor accepted the offer, and the following year envoys were sent by him to make a treaty of commerce at Tsargrad. The treaty was made and the Emperor gave oath to observe it, then he sent envoys to Kief and Igor took the oath. Those of his men who were pagans swore by Perun, the god of thunder, and by their weapons; those who were Christians gave oath in the church of Elias. This treaty, more favorable to the Greeks than that made with Oleg, contains the phrase “Russian land,” used then for the first time in history. Toward the end of that same year, 945, Igor went to the Drevlians, a forest tribe in the North-west, to collect tribute a second time. Learning of his approach, the Drevlians counseled together and said: “If a wolf attacks sheep he will devour the whole flock, unless he is killed; so this man will ruin us, unless we destroy him.” They seized Igor, bent down two trees, tied his feet to the top of one and his head to the other, then let them go; thus he was torn asunder. The Drevlians then sent envoys to Olga to justify their action, and propose that she should marry their prince. Olga, determined to avenge her husband, answered: “Your speech is pleasing to me. To-morrow I will receive you in the presence of all my people. When my messengers come in the morning, tell them that you will not go on horseback or on foot,—that you must be carried in your boats.” When the envoys were gone, Olga had a deep pit dug in the courtyard. Next morning she sent for her guests, who came in their boats borne on the shoulders of men. The Drevlians, from their lofty position, looked down proudly on the multitude; but when they arrived at the courtyard they, with their boats, were thrown into the pit and quickly covered with earth. Olga, keeping secret what had taken place, sent for a guard of honor to conduct her to the Drevlians. The first men of the tribe came; these she had burned up in a bath-house. Then she sent a message, saying: “I am on the road. Bring as much mead as you can to where my husband died. I wish to weep over his grave.” She came, with a part of her army, to where Igor was buried, and there she had a great mound raised, and celebrated the funeral feast. The Drevlians asked, “Where are our men?” She replied, “They are coming with my men.” The simple foresters, satisfied with this answer, went on feasting. When they had drunk themselves into helplessness, Olga’s warriors fell upon them and slew great numbers.
