The failure of the
1719 Rising meant many Jacobites viewed the Stuart cause as hopeless and sought to return home. Pardoning them worked for the government, since it was clear the
Highlands could not be governed without the co-operation of the clan chiefs. In addition, sales of confiscated property were either delayed by legal arguments or reduced by fictitious debts, with former rebels often aided in this process by their loyalist friends and neighbours. This built links of obligation and friendship between the two sides and explains the bitterness displayed after 1745 towards those like
Lord George Murray, pardoned for their roles in 1715 and 1719. Although many Scots remained opposed to the 1707 Union and the malt tax and Porteous riots showed a lack of sensitivity by the London government, these were minor issues; Glasgow, centre of the 1725 protests, remained resolutely anti-Jacobite in 1745. In March 1743, the Highland-recruited
42nd Regiment or Black Watch was posted to
Flanders to fight in the
War of the Austrian Succession, despite Forbes warning this was contrary to an understanding their service was restricted to Scotland. A short-lived mutiny was suppressed and the regiment gained an impressive fighting record during the next few years. By 1737, the exiled Stuart claimant
James Francis Edward Stuart was reportedly 'living quietly in Rome, having abandoned all hope of a restoration.' This changed in 1740 after the war placed Britain and France on opposing sides;
Louis XV proposed a landing in England in early 1744 to restore the Stuarts, primarily to divert British resources from Flanders. As demonstrated in
1708 and 1719, threatening an invasion was far more cost effective than an actual one and the plan was abandoned after the French fleet was severely damaged by winter storms in March. '' by
John Seymour Lucas, 1884; Forbes counselled against 'Unnecessary Severitys.' In August 1744,
Prince Charles met Jacobite agent
Murray of Broughton in
Paris, telling him he was "determined to come to Scotland ...though with a single footman". His arrival on
Eriskay on 23 July took both sides by surprise; even then, "the cold reality [is] that he was unwanted and unwelcomed". Despite being urged to return to France immediately, enough Scots were eventually persuaded and the
1745 Rising launched on 19 August. Forbes received confirmation of the landing on 9 August, which he forwarded to London. The military commander in Scotland
Sir John Cope had only 3,000 soldiers available, many untrained recruits and initially could do little to suppress the rebellion. Forbes instead used personal relationships to keep people loyal and though unsuccessful with some, many others stayed on the sidelines as a result. His efforts were recognised by both sides; a Jacobite commentator later wrote that 'had the Lord President been as firm a friend of the Stuarts as he was an opponent,...we should have seen an army of 18,000, not 5,000 invade England.' After the Jacobite entry into Edinburgh and their victory at
Prestonpans in September, Forbes and
John Campbell, Earl of Loudoun based themselves in Inverness with around 2,000 recruits, sending regular updates to
General George Wade in Newcastle. Acting on instructions from Lovat, the Frasers attempted to
kidnap Forbes in October, then attacked
Fort Augustus in December; Lovat was arrested but escaped without difficulty in early January. Forbes and Loudon relocated to the
Isle of Skye in early February after the Jacobites abandoned the
siege of Stirling Castle and retreated to Inverness. After the
Battle of Culloden in April ended the Rising, Forbes supported severe penalties for the leaders, especially repeat offenders like Murray and Lovat but counselled 'Unnecessary Severitys create Pity.' He opposed the
1746 Dress Act banning Highland attire, arguing enforcement of the 1716 Disarming Act was more important. This advice was largely ignored by
Cumberland, who wrote
...he is Highland mad...and believes once dispersed, the rebels are no more consequence than a London mob. When
Flora MacDonald was arrested and sent to London for helping Charles escape, Forbes arranged for her to be held in a private residence until released by the
Act of Indemnity in June 1747. Forbes was financially ruined by the Rising; his estate was badly damaged during the battle, while he was never reimbursed for the monies spent on behalf of the government. He died on 10 December 1747 and was buried in
Greyfriars Kirkyard, near to his brother John. The grave lies south of the church and is marked by a stone slab added in the 1930s by the
Saltire Society. A statue of him by
Louis-François Roubiliac was erected in the
Parliament House, Edinburgh by the
Faculty of Advocates in 1752. ==Legacy==
