Passage: As a young man Robert entered the army in 1626 and became an officer in Donald Mackay's regiment, serving first in Danish service and later in Swedish service where he highly distinguished himself during the Thirty Years' War on the continent, particularly during the Battle of Lutzen in 1632. According to 19th-century historian Alexander Mackenzie there were three Generals, eight Colonels, five Lieutenant-Colonels, eleven Majors and above thirty Captains, besides a large number of other soldiers all of the name Munro in the Swedish army during the Thirty Years' War. However, although there were numerous colonels and lower ranks bearing the name of Monro or Munro during the Thirty Years' War, none actually held the rank of general in any of the continental armies between 1618 and 1648. It was most likely this man recorded as a major in the regiment of Colonel Robert Monro in 1639 , just prior to the regiment's return to Scotland.
Besides the soldiers  and captains how many of the other ranks were there? How many Generals and Majors combined were there in the Swedish Army during the Thirty Years' War? How many years did the war last? How many years passed from when he became an officer in Donald Mackay's regiment to when the Battle of Lutzen began? Was he in the Danish service or the Swedish service first? What happened first, Robert serving in the Danish service or Swedish service? What was Robert's rank in the Danish army? What were the dates of the Thirty Years' War? When did the Thirty Years' War begin? When did the Thirty Years' War end? When did the first event happen? When did the second event happen? Where did Robert serve last, the Danish or Swedish service? Which had more in the army, the Captains or the Colonels?
