Following the Battle of Dunbar in 1650, over 4000 Scots had been captured and imprisoned. In fairly short order, 150 of the healthiest men were gathered, taken to London and then shipped on the Unity to New England, arriving in Massachusetts. These approximately 150 Scottish prisoners of war which arrived in Massachusetts Bay were a small remnant of the prisoners from the Battle of Dunbar which numbered in the thousands. Many perished in England or were banished to other countries to serve time.
This battle and its aftermath is detailed in my novel DARK DESTINY, book three of the Dark Birthright trilogy.
A sea voyage to the colonies is mentioned, as is the young man Peter Grant.
