Mackay's Regiment was one of the earliest Scottish regiments, being
raised in 1626 and serving in the latter stages of the Thirty Years War
in Germany on the Protestant side in the Swedish army. The great Swedish
king and soldier Gustavus Adolphus, an ardent admirer of Scottish
soldiers, incorporated the Regiment along with three other Scottish
regiments, into his celebrated Green Brigade. The regiment first saw
service under the King of Denmark, being raised by Sir Donald Mackay -
later Lord Reay - and suffering grievous losses defending Danish
territory against the advance of the Catholic Imperialists. When Sweden
entered the war on the Protestant side, the regiment enlisted with him
and drove deep into Germany, benefiting from the revolutionary battle
tactics introduced by Gustavus. They took part in Gustavus's great
triumph at Breitenfeld, and also in the hard-won victory at Lutzen in
which the Swedish king was killed. At the subsequent Swedish defeat of
Nordlingen, the regiment lost so many men that it was reduced to company
strength. At the end of the war, the remnants of the regiment were
amalgamated into the Royal Scots. This absorbing book will interest all
members of the Clan Mackay and anyone keen on Scotland's proud military
history.
