Input: Consider Input: Question: What was the founding date of the team Foster played against in the 2001 FA Trophy final? Passage:After a short period in Scotland, Foster returned to English football with Doncaster Rovers where his opportunities were limited, though he had a spell with Ilkeston Town on loan. In 2001, he signed for Forest Green Rovers in the Conference National. He made well over 100 appearances for the club and had a spell as captain. He also appeared for Forest Green in the 2001 FA Trophy final at Villa Park but was on the losing side in a 1-0 defeat to Canvey Island. He was highly regarded amongst the supporters at The Lawn and many were sad to see him leave when he departed for Halifax Town in 2004. He made just under 100 league appearances for Halifax at The Shay before a move in 2007 to Oxford United.

Input: Consider Input: 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.
