Olga then led her army to Iskorosten (what is today Korosten), the city where her husband had been slain, and laid siege to the city. The siege lasted for a year without success, when Olga thought of a plan to trick the Drevlians. She sent them a message: “Why do you persist in holding out? All your cities have surrendered to me and submitted to tribute, so that the inhabitants now cultivate their fields and their lands in peace. But you had rather tide of hunger, without submitting to tribute.”[12] The Drevlians responded that they would submit to tribute, but that they were afraid she was still intent on avenging her husband. Olga answered that the murder of the messengers sent to Kiev, as well as the events of the feast night, had been enough for her. She then asked them for a small request: “Give me three pigeons...and three sparrows from each house.”[12] The Drevlians rejoiced at the prospect of the siege ending for so small a price, and did as she asked.
Olga then instructed her army to attach a piece of sulphur bound with small pieces of cloth to each bird. At nightfall, Olga told her soldiers to set the pieces aflame and release the birds. They returned to their nests within the city, which subsequently set the city ablaze. As the Primary Chronicle tells it: “There was not a house that was not consumed, and it was impossible to extinguish the flames, because all the houses caught fire at once.”[12]As the people fled the burning city, Olga ordered her soldiers to catch them, killing some of them and giving the others as slaves to her followers. She left the remnant to pay tribute.
