When the Covenanters became allies of the English
Parliamentarians, Montrose was given a commission as
King Charles's Lieutenant General in Scotland. He was able to raise an army consisting of regiments of Irish soldiers sent to Scotland by the
Irish Confederates and shifting numbers of Highland clansmen. With these troops, Montrose had won a remarkable series of victories in the year preceding the Battle of Philiphaugh. The last of these was at
Kilsyth, which destroyed the last Covenanter army in Scotland and put the lowland towns at his mercy. Montrose refused to allow his army to loot
Glasgow, instead accepting a sum of £500 from the Town Council as pay for his soldiers. He then summoned a
Parliament to be held in
Glasgow. The Council complained at the cost which would be involved and asked to be excused the levy of £500. Montrose agreed, leaving his army without pay. Although Montrose intended to strike into England to aid the King's cause there, the Highlanders under
Alasdair MacColla who made up most of Montrose's infantry refused to go any further south leaving their traditional foes, the
Campbells, in their rear. At the same time, Montrose appointed the former prisoner, the
Earl of Crawford as his Lieutenant General of Horse. Most of his horsemen were
Gordons under Lord
James Aboyne. Affronted by Crawford's appointment, they too left the army. Montrose hoped to gain recruits from the
Borders, and marched south with only 500 musketeers from his Irish
Catholic regiments and a small troop of horse. He made for
Kelso, but found that only a few Borders gentry joined his army instead of the thousands of recruits he expected. Meanwhile, the
Earl of Leven, who commanded the main Scottish Covenanter Army in England, had heard of the result of the
Battle of Kilsyth, and sent
Sir David Leslie, the Lieutenant General of Horse, back into Scotland with all the cavalry he could muster. Leslie collected reinforcements from Covenanter garrisons in
Newcastle upon Tyne and
Berwick, and crossed the border on 6 September, with 5,000 horse and
dragoons and 1,000 infantry. He marched along the east coast intending to cut off Montrose from the Highlands, but learned (possibly from the turncoat Earls of Home and Roxburgh) of Montrose's position and strength, and turned south to intercept him. ==Battle==
