“The rout would have been total, but for the three out-flanking regiments.  These not having been opposed by any of the clans, having a ravine in front, and deriving some support from a small body of dragoons, stood their ground under the command of General Huske and Brigadier Cholmondley.  When the Highlanders went past in pursuit, they received a volley from this part of the English army, which brought them to a pause, and caused them to draw back to their former ground, their impression being that some ambuscade was intended.  This saved the English army from destruction.  A pause took place, during which the bulk of the English infantry got back to Falkirk.  It was not until Lord George Murray brought up the second line of his wing and the pickets, with some others on the other wing, that General Huske drew off his party, which he did in good order.”

The seat of war was now removed to the North.  The month of April, 1746, found Prince Charles in possession of Inverness, with an army sorely dwindled in numbers, and in great want of necessaries and provisions.  Many of the Highlanders had retired for the winter to their native glens, and had not yet rejoined the standard.  The Duke of Cumberland, who now commanded the English army, with a reputation not diminished by the unfortunate issue of Fontenoy, was at the head of a large body of tried and disciplined troops, in the best condition, and supported by the powerful arm of artillery.  He effected the passage of the Spey, a large and rapid river which intersects the Highlands, without encountering any opposition, and on the 15th of the month had arrived at Nairn, about nine miles distant from the position occupied by his kinsman and opponent.  His superiority in point of strength was so great that the boldest of the insurgent chiefs hesitated as to the policy of giving immediate battle, and nothing but the desire of covering Inverness prevented the council from recommencing a further retreat into the mountains, where they could not have been easily followed, and where they were certain to have met with reinforcements.  As to the Prince, his confidence in the prowess of the Highlanders was so unbounded, that, even with such odds against him, he would not listen to a proposal for delay.

There yet remained, says Mr. Chambers, before playing the great stake of a pitched battle, one chance of success by the irregular mode of warfare to which the army was accustomed, and Charles resolved to put it to trial.  This was a night-attack upon the camp of the Duke of Cumberland.  He rightly argued that if his men could approach without being discovered, and make a simultaneous attack in more than one place, the royal forces, then probably either engaged in drinking their commander’s health (the 15th happened to be the anniversary of the Duke’s birthday, and was celebrated as such by his army), or sleeping off the effects of the debauch, must be completely surprised and cut to pieces, or at least effectually routed.  The time appointed for setting out upon the march was eight in the evening, when daylight should have completely disappeared, and, in the mean time, great pains were taken to conceal the secret from the army.
