Question: How long had Jacob Shaw been captain of the regiment before Learmonth entered service? Passage:George Learmonth, baptized by Russian Orthodox Church as Yuri Andreevich Lermont (; 1590s–1633) was a Scottish soldier in Russian service. Entered Russian service in 1613 as the ensign in regiment of captain-rittmeister Jacob Shaw. At least six of former members of the Belaia garrison, including George Learmonth, helped decisively turn back Prince Wladyslaw’s troops in intense fighting at Moscow’s Arbat Gates of Bely Gorod during defending Moscow against a Polish army. In that battle, Ensign George Learmonth’s bravery was on display ‘for all to see’. When Lieutenant David Edwards was killed in the defence of Moscow, the Irish soldiers in his company immediately petitioned to have George Learmonth replace him. Newly promoted Lieutenant Yuri Lermont received fifteen rubles per month. During the Smolensk War (1632–1634) he's Rittmeister of Moscouvite Reiters regiment of Charles d'Ebert, under command of Prince Semyon Prozorovsky, died in battle against units of Field Hetman of Lithuania Krzysztof Radziwiłł on 30 August 1633.

Question: How long did the Battle of Jumonville Glen last? Passage:The Ohio Country located between Britain's Thirteen Colonies and France's New France saw France and Britain clash. In 1753 the French sent an expedition south from Montreal that began constructing forts in the upper reaches of the Ohio River. In 1754 the Province of Virginia sent the Virginia Regiment led by George Washington to the area to assist in the construction of a British fort at present-day Pittsburgh, but the larger French force had driven away a smaller British advance party and built Fort Duquesne. Washington and some native allies ambushed a company of French scouts at the Battle of Jumonville Glen in late May 1754. In the skirmish the French envoy Joseph Coulon de Jumonville was left dead leading to a diplomatic incident. The French responded in force from Fort Duquesne, and in July Washington was forced to surrender at the Battle of Fort Necessity. Despite the conflict between them, the two nations were not yet formally at war.
