Question: Passage: In July 1449 Esen Tayisi  of the Mongols launched a large-scale, three-pronged invasion of China with his puppet khagan Toqtaq-Buqa. He personally advanced on Datong  in August. The eunuch official Wang Zhen, who dominated the Ming court, encouraged the 22-year-old Zhengtong Emperor to lead his own armies into battle against Esen. The size of Esen's army is unknown but a best guess puts it at some 20,000 men. The Ming army of about 500,000 was hastily assembled; its command was made up of 20 experienced generals and a large entourage of high-ranking civil officials, with Wang Zhen acting as field marshal. On August 3 Esen's army crushed a badly supplied Chinese army at Yanghe, just inside the Great Wall. The same day the Emperor appointed his half-brother Zhu Qiyu as regent. The next day he left Beijing for Juyong Pass. The objective was a short, sharp march west to Datong via the Xuanfu garrison, a campaign into the steppe and then a return to Beijing by a southerly route through Yuzhou. Initially the march was mired by heavy rain. At Juyong Pass the civil officials and generals wanted to halt and send the emperor back to Beijing, but their opinions were overruled by Wang Zhen. On August 16, the army came upon the corpse-strewn battlefield of Yanghe. When it reached Datong on August 18, reports from garrison commanders persuaded Wang Zhen that a campaign into the steppe would be too dangerous. The "expedition" was declared to have reached a victorious conclusion and on August 20 the army set out back toward China proper.
Question: When was the Zhengtong Emperor born?

Answer: date


Question: Passage: During World War II, the Lingayen Gulf proved a strategically important theatre of war between American and Japanese forces. On 22 December 1941, the Japanese 14th Army under Lieutenant General Masaharu Homma landed on the Eastern part of the gulf at Agoo, Caba, Santiago and Bauang, where they engaged in a number of relatively minor skirmishes with the defenders, which consisted of a poorly equipped contingent of predominantly Filipino and American troops, and managed to successfully invade and occupy the gulf. Following the defeat, the next day General MacArthur issued the order to retreat from Luzon and withdraw to Bataan. For the next three years, the gulf remained under Japanese occupation prior to the Lingayen Gulf Landings. At 09:30 on 9 January 1945, the U.S. 6th Army conducted an amphibious landing on the gulf, following a devastating naval bombardment, with 68,000 troops landing on the first day alone, and a total of 203,608 in following landings along a 20 mi  beachhead, stretching from Sual, Lingayen, and Dagupan  in the west, and San Fabian  in to the east. Despite the Americans' success in driving out the Japanese army encamped at the Gulf, the Americans suffered relatively heavy losses, particularly on their convoys due to Japanese kamikaze suicide attacks. From 4 through 12 January, a total of 24 ships were sunk and 67 damaged by kamikaze planes, including the battleships USS Mississippi and Colorado , the heavy cruiser USS Louisville , the light cruiser USS Columbia, and the minesweepers USS Long and Hovey. Following the amphibious landings, the Lingayen Gulf was turned into a vast supply depot for the rest of the war to support the American and Filipino assaults on Manila and the rest of Luzon, and thence to Okinawa.
Question: How many places did Lieutenant General Masaharu Homma land his troops?

Answer: number
