[Q]: Passage: The Cham also requested Ming China to intervene by helping bring the Vietnamese back in line by force and demarcate the border between Champa and Vietnam. China, however, only verbally rebuked the Vietnamese for its incursion, which the Vietnamese ignored, proceeding with its attack and plan to destroy its rival. The Vietnamese then carried out its campaign. On November 28, 1470, Le Thanh Tong formally launched his attack as a 100,000-strong Vietnamese naval expedition set out that day, followed by another Vietnamese army consisting of 150,000 men on December 8. The Vietnamese army was reorganized to copy the Chinese army, armed with gunpowder weapons. Le Thanh Tong raised a total of 300,000-strong army in the battlefied and, significantly outnumbering the 100,000-strong Cham army. This came at a massive financial cost since it drained the Vietnamese treasury of 1,000 gold liang each day. However, it decisively won the war. 
Question: After formally launching an attack, how many days later did Le Thanh Tong increase his army? 
Answer type: Number 
[A]: 10.

[Q]: 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 
[A]:
9.
