James Graham, the Marquis of Montrose, the 'Great Montrose' won a series of brilliant, almost impossible victories over the Covenanters in 1644-45 that is remembered as the 'Year of Miracles'. Such a run of near impossible victories wouldn't be seen again in British history until Leicester won the league in 2016. Montrose fought to make himself 'Master of Scotland' but like Alex Salmond it all came crashing down around him, not because he was 'grabby' or anything, his Royalist cause lost support and unlike Ruth Davidson he didn't have a peerage in the House of Lords to fall back on now he wasn't as popular in Scotland.
