At the beginning of the 17th century there were many thousands of Scottish soldiers of fortune in Flanders and the Low Countries supporting the Calvinist Dutch in their struggle against Spain during the Dutch Revolt, fighting throughout northern Europe, especially in Germany, Poland, and Russia. In the aftermath of the Thirty Years War, many Scots remained in foreign service or settled permanently on the continent. This work, based on original and secondary sources, identifies between 2,500 and 3,000 Scots who served in a variety of military theaters in Europe and in the Americas. Mr. Dobson identifies each combatant by name, a location, a date, and the source, and in a number of cases by the names of next of kin, vessels traveled on, place of origin in Scotland, or other particulars.
