Flower of Scotland

Dad29 sends the story story of a priest from the Society of Jesus who ministered to his flock during those hours when Catholicism was banned in Scotland, then joined the Jacobite army that invaded England in the '45.

Fr. Alexander Cameron was a convert to the Faith who served the exiled Stuart king of England and Wales at his court in Rome. Cameron later became a Jesuit priest and returned to Scotland to minister to the illegal and underground Catholic Church in his native land. For four years he served as a “heather priest” in the Scottish Highlands, risking arrest and the harshest of weather conditions to provide spiritual succor and the sacraments to his outlawed flock. 

The "harshest of weather conditions" just means that he was a priest in the Highlands of Scotland.

The rest of the story is impressive, though.
