he famous Chevalier Johnstone,
whom he soon adopted into his service. This young soldier, whose pen has
supplied memoirs of the Rebellion of 1745, and upon whose statements
much of the reported merits of Lord George Murray rests, was the only
son of a merchant in Edinburgh, and the descendant of an ancient and
well-connected family. By the marriage of his sister he was nearly
related to the House of Rollo; and, from these and other circumstances,
he mingled with the best society in his native city.

Having been educated in Jacobite and Episcopalian principles, young
Johnstone hailed with delight the arrival of Prince Charles: he resolved
instantly to join his standard. Escaping from Edinburgh, he hastened to
Duncrub, the seat of Lord Rollo, near Perth. Here he awaited the arrival
of the young Chevalier; and here he was introduced by his cousins, the
daughters of Lord Rollo, to the Duke of Perth and to Lord George Murray.
The Chevalier Johnstone was one of the first Low-countrymen that joined
the standard of Charles Edward.

Lord George Murray very soon discovered that the requisites for forming
a good soldier and an active partizan were centred in young Johnstone.
For the former he was qualified by an open and impetuous character,
generally combined with a desperate courage. The jollity and licence of
the Cavalier school, which characterized Johnstone, did not materially
detract from, but added rather to the popularity of his character. As a
partizan, he has proved his zeal by his Memoirs, which afford a sample
of much heat and prejudice, and which have, in upholding Lord George
Murray, done an injury to the memory of Charles Edward, of which the
adversaries of his cause have not failed to take advantage. To many
errors of character, and to some egotism, the Chevalier Johnstone, as he
came to be called in after-life, united a kind heart and an enthusiastic
disposition. He acted for a considerable time as aide-de-camp to Lord
George Murray, and afterwards in the same capacity with the Prince. But
his liveliest admiration appears to have been directed towards the
general who has been classed with Montrose and Dundee,[28] and no
subsequent service under other masters ever effaced his impression of
respect and confidence to Lord George Murray. After the battle of
Preston-Pans Johnstone received a captain's commission from the Prince:
and, exhausted with his duties as aide-de-camp, he formed a company,
with which he joined
