Siege of Fort Augustus (March 1746)

[2] Despite being well-supplied, Fort George surrendered without fighting; its governor, Major Grant, a close relative of the Jacobite Lord Lovat, was later court-martialled and dismissed.

[3] Square in plan with angled bastions on each corner, the fort was designed "more ... for ornament than strength", as a demonstration of the government presence in the Scottish Highlands.

The walls were weak, while the six-pounder guns that provided defensive fire were installed on top of the four bastions, in full view of an attacking force.

The garrison capitulated on 1 March without any casualties, and Wentworth was considered to have surrendered too early; he was subsequently court-martialled and dismissed from the army.

[6] The Jacobites moved on to Fort William, the last government strong point along the Great Glen, a much stronger facility.
