Question: How long was the Nazi Party around for before Stahlecker joined it? Passage:On 1 May 1932, Stahlecker joined the Nazi Party (no. 3,219,015) as well as the SS (no. 73,041). On 29 May 1933, he was appointed deputy director of the Political Office of the Wurttemberg State Police. In 1934, he was appointed head of the Gestapo in the German state of Wurttemberg and soon assigned to the main office of the Sicherheitsdienst (SD). On 11 May 1937, he became head of the Gestapo in Breslau. After the incorporation of Austria in 1938, Stahlecker became SD chief of the Danube district (Vienna), a post he retained even after being promoted to SS-Standartenfuhrer. In the summer of 1938, Stahlecker became Inspector of the Security Police in Austria, succeeding Gestapo chief Heinrich Muller in that position. As of 20 August 1938, Stahlecker was the formal head of the Central Agency for Jewish Emigration in Vienna, though its de facto leader was Adolf Eichmann. Differences of opinion with Reinhard Heydrich motivated Stahlecker to move to the Auswartiges Amt (Foreign Office), after which he held posts as the commander of the Security Police and SD in the Protectorate of Bohemia and Moravia under SS-Brigadefuhrer Karl Hermann Frank. In mid-October 1939, Eichmann and Stahlecker decided to begin implementation of the Nisko Plan.

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 15441549, 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.
