In 1642, the English Civil War broke out between the King, Charles I, and the Parliament. While the war began in England, both sides enlisted the help of Scotland. The Parliamentarians and Covenanters joined forces, while other parts of Scotland declared for the King. One noble to take up the King's cause was the Marquis of Huntly. He quickly raised his own regiment, known as the Strathbogie Regiment for the service of the King's agent in Scotland, the Marquis of Montrose. The Strathbogie Regiment followed Montrose's army, and was key at the battle of Auldearn, leading the counter-attack on Auldearn village. My brother and I built the flag of the Strathbogie Regiment using Wikipedia's Rampant Lion and the crown from Charles I's Foot Guards, Lieutenant-Colonel's company. Thanks! While Scots flags are poorly recorded, this one, thankfully, is recorded as (1600's spelling has been kept intact) "ane red rampand lion, having ane croun of gold above his head and C. R. for Carolus Rex, haveing this motto, For God, The King, and Against All Traittouris, and benethe, God Save the King."
