Despite receiving no commission from James to start the rising, the Earl of Mar sailed from London to Scotland, and on 27 August at
Braemar in
Aberdeenshire held a council of war with other Jacobite leaders. On 6 September at Braemar, Mar raised the standard of "James the 8th and 3rd", acclaimed by 600 supporters.
Parliament responded with the passage of a
Habeas Corpus Suspension Act permitting the arrest without trial of accused Jacobites, and authorized the seizure and redistribution of their lands in favour of any tenants willing to swear an oath of loyalty to George I. Indeed, records show that at least some of Mar's tenants traveled to London with the hopes of proving their loyalty and receiving parcels of his estate. In northern Scotland, the Jacobites scored a number of victories. They took
Inverness,
Gordon Castle, Aberdeen and further south,
Dundee, although they were unable to capture
Fort William. In
Edinburgh Castle, the government stored arms for up to 10,000 men and a sum of £100,000 paid to the Scottish parliament for agreeing to Union with England. Lord Drummond, with 80 Jacobites, tried under the cover of night to take the Castle, using a ladder. However, the ladder proved too short and the men were stranded until early morning, which point they were discovered and arrested. By October, Mar's force, numbering nearly 20,000, had taken control of all Scotland above the
Firth of Forth, apart from
Stirling Castle. However, Mar proved an indecisive general, and the Jacobite capture of
Perth and the move south by 2,000 men were probably at the initiative of subordinates. Mar's hesitation to commit his forces gave the Hanoverian commander, the
Duke of Argyll, precious time to increase his strength with reinforcements from the
Irish Garrison. On 22 October, a commission from James appointed Mar commander-in-chief of the Jacobite army. His forces outnumbered Argyll's Hanoverian army by three to one, and Mar decided to march on Stirling Castle. On 13 November the two forces joined
battle at Sheriffmuir. The fighting was indecisive, but near the end the Jacobites numbered 4,000 to Argyll's 1,000. Mar's force began to advance on Argyll, who was poorly protected, but Mar did not close in, possibly believing that he had won the battle already (Argyll had lost 660 men, three times as many as Mar). Instead, the Jacobites retreated to Perth for rest. On the same day as the Battle of Sheriffmuir, Inverness surrendered to Hanoverian forces, and a smaller Jacobite force led by
Mackintosh of Borlum was
