Input: Consider Input: Passage: After their success in the Morea, the Ottomans moved against the Venetian-held Ionian Islands. They occupied the island of Lefkada , which the Venetians had taken in 1684, and the fort of Butrinto opposite the city of Corfu. On 8 July 1716, an Ottoman army of 33,000 men landed on Corfu, the most important of the Ionian islands. Despite an indecisive naval battle on the same day, the Ottoman land army continued its disembarkment and advanced towards the city of Corfu. On 19 July, after capturing the outlying forts of Mantouki, Garitsa, Avrami and of the Saviour, the siege began. The defence was led by Count Johann Matthias von der Schulenburg, who had roughly 8,000 men at his command. The extensive fortifications and the determination of the defenders withstood several assaults. After a great storm on 9 August—which the defenders attributed to the intervention of Corfu's patron saint, Saint Spyridon—caused significant casualties among the besiegers, the siege was broken off on 11 August and the last Ottoman forces withdrew on 20 August. 
Question: How many days after the siege was broken off did the Ottoman forces withdraw? 
Answer type: Number 

Output: 9.


Input: Consider Input: Passage: The Iroquois attacked the Neutral Nation in 1650. By the end of 1651, they had completely driven the tribe from traditional territory, killing or assimilating thousands. At the time, the Neutrals inhabited a territory ranging from the present-day Niagara Peninsula, westward to the Grand River valley. In 1654 the Iroquois attacked the Erie, but with less success. The war between the Erie and the Iroquois lasted for two years. By 1656 the Iroquois had almost completely destroyed the Erie confederacy, whose members refused to flee to the west. The Erie territory was located on the southeastern shore of Lake Erie and was estimated to have 12,000 members in 1650. Greatly outnumbered by the tribes they had subdued, the Iroquois had been able to achieve their victories through the use of firearms purchased from the Dutch. 
Question: How many years did it take for the Iroquois to drive the Neutral Nation from traditional territory?
