Background: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.
Context: Ma He was captured by the Ming armies at Yunnan in 1381. General Fu Youde saw Ma He on a road and approached him in order to inquire about the location of the Mongol pretender. Ma He responded defiantly by saying that the Mongol pretender had jumped into a lake. Afterwards, the general took him prisoner. He was castrated before being placed in servitude of the Prince of Yan at age 10, although another source indicates the castration occurred in 1385.  Ma was sent to serve in the household of Zhu Di, the Prince of Yan, who later became the Yongle Emperor. Zhu Di was eleven years older than Ma. Since 1380, the prince had been governing Beiping (later Beijing), which was located near the northern frontier where the hostile Mongol tribes were situated. Ma would spend his early life as a soldier on the northern frontier. He often participated in Zhu Di's military campaigns against the Mongols. On 2 March 1390, Ma accompanied the Prince when he commanded his first expedition, which was a great victory as the Mongol commander Naghachu surrendered as soon as he realized he had fallen for a deception.  Eventually, he would gain the confidence and trust of the prince. Ma was also known as "san bao" during the time of service in the household of the Prince of Yan. This name was a reference to the Three Jewels (San Bao , triratna) in Buddhism. There is also document saying his name could be San Bao  (lit. "Three Protections", also pronounced san bao). Ma received a proper education while at Beiping, which he would not have had if he had been placed in the imperial capital Nanjing, as the Hongwu Emperor did not trust eunuchs and believed that it was better to keep them illiterate. Meanwhile, the Hongwu Emperor purged and exterminated many of the original Ming leadership and gave his enfeoffed sons more military authority, especially those in the north like the Prince of Yan.
Question: Why was he captured?
Answer: Ma He responded defiantly by saying that the Mongol pretender had jumped into a lake. Afterwards, the general took him prisoner.

Problem: Background: Richard I (8 September 1157 - 6 April 1199) was King of England from 1189 until his death. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine. He was known as Richard Coeur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior.
Context: In September 1190 Richard and Philip arrived in Sicily. After the death of King William II of Sicily his cousin Tancred had seized power and had been crowned early in 1190 as King Tancred I of Sicily, although the legal heir was William's aunt Constance, wife of the new Emperor Henry VI. Tancred had imprisoned William's widow, Queen Joan, who was Richard's sister, and did not give her the money she had inherited in William's will. When Richard arrived he demanded that his sister be released and given her inheritance; she was freed on 28 September, but without the inheritance. The presence of foreign troops also caused unrest: in October, the people of Messina revolted, demanding that the foreigners leave. Richard attacked Messina, capturing it on 4 October 1190. After looting and burning the city Richard established his base there, but this created tension between Richard and Philip Augustus. He remained there until Tancred finally agreed to sign a treaty on 4 March 1191. The treaty was signed by Richard, Philip and Tancred. Its main terms were:  Joan was to receive 20,000 ounces (570 kg) of gold as compensation for her inheritance, which Tancred kept.  Richard officially proclaimed his nephew, Arthur of Brittany, son of Geoffrey, as his heir, and Tancred promised to marry one of his daughters to Arthur when he came of age, giving a further 20,000 ounces (570 kg) of gold that would be returned by Richard if Arthur did not marry Tancred's daughter.  The two kings stayed on in Sicily for a while, but this resulted in increasing tensions between them and their men, with Philip Augustus plotting with Tancred against Richard. The two kings finally met to clear the air and reached an agreement, including the end of Richard's betrothal to Philip's sister Alys (who had supposedly been the mistress of Richard's father Henry II).
