question:
Question: How old was the military engineer who scouted around Leith during the siege? Passage:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 1544–1549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.

Question: Who was drafted immediately before Bergevin the year he joined the Blackhawks? Passage:Bergevin was drafted by the NHL's Chicago Blackhawks in the 1983 NHL Entry Draft, third round, 59th overall. After a junior career with the Chicoutimi Saguenéens of the Quebec Major Junior Hockey League (QMJHL), he made the Black Hawks in 1984 and played with Chicago for the next five seasons before being traded to the New York Islanders. His career with the Islanders was brief, and he spent much of that time with their American Hockey League (AHL) affiliate Springfield Indians, whom he helped lead to consecutive Calder Cup championships in 1990 and 1991. In the 1991 season he was traded to the Hartford Whalers and became a fan favorite for his skilled checking. The 1991–92 was his best season statistically, scoring 7 goals and 17 assists for 24 points.
