The victors obtained possession of Perth, and obtained considerable sums of money, as well as ample supplies of arms and ammunition. But those advantages were to be balanced against an almost insurmountable inconvenience that uniformly attended a Highland army. The clans could be in no respect induced to consider themselves as regular soldiers, or to act as such. Even so late as the year 1745-6, when the Chevalier Charles Edward, by way of making an example, caused a soldier to be shot for desertion, the Highlanders, who composed his army, were affected as much by indignation as by fear. They could not conceive any principle of justice upon which a man’s life could be taken, for merely going home when it did not suit him to remain longer with the army. Such had been the uniform practice of their fathers. When a battle was over, the campaign was, in their opinion, ended; if it was lost, they sought safety in their mountains--if won, they returned there to secure their booty. At other times they had their cattle to look after, and their harvests to sow or reap, without which their families would have perished for want. In either case, there was an end of their services for the time; and though they were easily enough recalled by the prospect of fresh adventures and more plunder, yet the opportunity of success was, in the meantime, lost, and could not afterwards be recovered. This circumstance serves to show, even if history had not made us acquainted with the same fact, that the Highlanders had never been accustomed to make war with the view of permanent conquest, but only with the hope of deriving temporary advantage, or deciding some immediate quarrel. It also explains the reason why Montrose, with all his splendid successes, never obtained any secure or permanent footing in the Lowlands, and why even those Lowland noblemen and gentlemen, who were inclined to the royal cause, showed diffidence and reluctance to join an army of a character so desultory and irregular, as might lead them at all times to apprehend that the Highlanders securing themselves by a retreat to their mountains, would leave whatever Lowlanders might have joined them to the mercy of an offended and predominant enemy. The same consideration will also serve to account for the sudden marches which Montrose was obliged to undertake, in order to recruit his army in the mountains, and for the rapid changes of fortune, by which we often find him obliged to retreat from before those enemies over whom he had recently been victorious. If there should be any who read these tales for any further purpose than that of immediate amusement, they will find these remarks not unworthy of their recollection.
