For the purpose of defraying the expenses entailed by a campaign, recourse was had to extraordinary taxation. In 1550, for instance, the Privy Council ordained that "for resisting of our auld ynemyis of Ingland, the defence of the West Borders, and the repairing of a fort of strength in the town of Annan, the sum of £4000 should be raised and uplifted of the prelates and clergy of the realm. If the amount were "thankfullie payit and debursit", exemption from further taxation for the next year was promised.

To meet the requirements of the transport service, certain districts were laid under requisition. Thus, for the same campaign, the sheriffs of Edinburgh principal, Edinburgh lying within the constabulary of Haddington, Selkirk, and Lauderdale, were called upon to assist and concur with the Lairds of Lethington, Whittingham, Elphinstone, Trabroun, and Wauchton, in devising measures for furnishing the oxen and pioneers required for the forthbringing of the munition and artillery to the host and army which was to assemble in Edinburgh.

It was not solely for the defence of their own country that Scotsmen were obliged to bear arms. Occasion might arise when, in conformity with the "old leagues, bands, amity and alliance" which were supposed to have been entered upon by King Achaus and the Emperor Charlemagne, and to have been renewed and confirmed by every king and prince since that time, Scotland was obliged to furnish a contingent for the support of the Most Christian King. Such was the case in 1552. In the month of November of that year, the Regent Arran and the Lords of the Secret Council ordained that every 40-mark land, whether it were royal, temporal, or spiritual, should supply "one able, sufficient footman, well furnished, clad in new hose and a new doublet of canvas at the least, with a jack of plate, steel bonnet, splint sleeves of mail or plate, with a spear of six ells long or thereby". Every burgh within the realm was to provide a company consisting of 300 men, who were, as far as possible, to be hagbutters, furnished with powder flask, morsing horn, and all other gear belonging thereto. Two further companies of footmen were likewise to be raised in the highland parts of the realm, within the bounds of Lord Huntly's lieutenancy. Horsemen to the number of 400, each having "ane dowbill horse", were to be supplied by the bishops, abbots, priors, and prelates, earls, lords, and barons of the Borders and Lowlands. Gilbert, Earl of Cassillis, was appointed Lieutenant-General of the army, and Patrick, Lord Ruthven, Colonel of the footmen. The subordinate officers numbered fifty-five. The expense of the expedition was to be borne by the King of France.[290]

It was not only when Scotland was engaged in actual warfare, either on her own account or as the ally of France, that she required to call out her fighting men. The state of the country was such that the "fencibles" of some district might, at any moment, be required to take the field. Within less than a decade—between 1569 and 1578—there were at least twelve local levies. The first and five others of them, that is to say, a full half of the whole number, were raised for purposes similar to those indicated by an Act of Privy Council, in September, 1569, "to pass forthward for pursuit and invasion of the thieves, traitors, and rebellious subjects, inhabitants of the bounds of the Middle and West Wardencies". For such an expedition as that, there were called out "all and sundry his Majesty's lieges betwixt 40 and 16 years, and other fencible persons" dwelling in 12 sheriffdoms, 2 stewartries, and 3 bailliries. And they were required to assemble, not only "weill bodin in feir of weir"—the current phrase for complete fighting equipment—but also to bring with them twenty days' victuals and provisions, and to provide themselves with tents to lie in the fields.

As it was impossible for every man to carry with him twenty days' provisions otherwise than in the shape of money wherewith to buy them, a commissariat of some kind became a matter of necessity. To provide it, the inhabitants of some town might be required, as was the case with those of Glasgow, in 1572, "to follow the army where it shall repair, with bread, ale, and all other kinds of vivers for men and horse, which shall be bought from them with ready money and thankful payment". If circumstances made it more convenient, a number of burghs, towns, and other places where "hostelry was used" were informed beforehand, by public proclamation, that they would have to "prepare and have in readiness, baked bread, brewed ale, wine, and all other manner of horse meat and men's meat, and address them to transport and carry the same, by land or sea, to the camp, where it shall happen to be, there to be sold upon sufficient and good prices". If, as might be the case in the "countries most ewest of the Borders", lochs or rivers should have to be crossed or otherwise utilized for the purpose of the expedition, commandment and direction was given to all and sundry owners, masters, and skippers of ships, barks, "birlingis", boats, and other vessels meet for ferrying, to have their craft prepared and in full readiness to receive, carry, and transport men, munition, horses, victuals, or other warlike provisions to such place as should be specially appointed. For disobedience to any of the orders issued for the purpose of levying an expeditionary force or of furthering its movements and operations, the penalty to be imposed was always the same, "forfeiture of life, lands, and goods".

The last phase in the development of the old Scots army began at the death of James VI. Shortly after the accession of his successor, the Estates issued a proclamation which had for its object the revival of "that lovable custom of wapenshawings" which "the laziness of the people themselves", but "specially the sloth and careless negligence" of the magistrates whose office it was to make arrangements for those inspections, had allowed to lapse. And the reason given for this renewal of interest in the ancient institution was contained in a reference to the "universal combustion and bruittis, and rumours of foreign preparation throughout Christendom". But nothing more practical was yet to come of it than an order for the holding of a muster. Nearly twenty years were to elapse before the same Estates were moved to give "their most serious consideration" to the reorganization of the national forces. This had become necessary by reason of "the great and imminent danger of the true Protestant religion and of the peace of the kingdom from the treacherous and bloodie plots, conspiracies, attempts, and practices of papists, prelates, malignants, and their adherents". In order to put the kingdom, with all possible speed, in a posture of defence, order was given that all fencible persons within sixty and sixteen years of age, should provide themselves with forty days' provisions of all sorts, in the most substantious manner, for horse and foot, with tents and all other furnishing requisite; that horsemen should be armed with pistols, broadswords, and steel caps; that where those arms could not be had, jacks or secrets, lances, and steel bonnets, and swords should be substituted for them. Footmen were to be armed with musket and sword, or pike and sword; but, failing these, they were to be furnished with halbards, Lochaber axes, or Jedburgh staffs, and swords. Colonels of horse and foot, and Committees of War were appointed in each sheriffdom, and were enjoined to form "their whole fencible persons into regiments, foot companies, and horse troops". The men were to be "drilled and exercised in managing their arms—every regiment once in the month, every company and troop once in the week". The captains of each company were to be provided with colours and drums, and the "rootmasters", or captains of horse, with trumpets and cornets. For the purpose of enforcing this Act, another was passed in the following year, again requiring all to arm, under a penalty of £20 to be paid by those who, being in a position to buy a musket and sword, should yet be found unprovided with them. Those who, though able to purchase a pike, neglected to do so, were to be fined 10 marks. Yeomen or servants lacking the means to provide themselves with the weapons prescribed by the Act were to be equipped by their respective heritors or masters. Further, the Committees of War in each shire were called upon to acquire and store, two pounds weight of powder and four pounds weight of match and ball, for every fencible person within their district.

It was at this time, too, that the first Act dealing with desertion from the army was passed. It gave strict injunctions to the Colonels and Committees of War to apprehend all those, both of horse and foot, who ran away from their colours, and empowered them, if they thought it expedient for the good of the army, to "decimate the fugitives, and cause hang the tenth man". If there were less than ten offenders, one might still be put to death, "for terrifying others"; and if there were only one, he might be made to suffer the extreme penalty.

Milder legislation originated at this time, too. It was in 1645 that an Act "in favour of lamed soldiers" promised maintenance upon the public charges to all who were so hurt and wounded in the defence of the public cause as to be unfit for their ordinary employment; and that another appointed a Committee to devise measures for the relief of the widows and orphans of those who fell. And so anxious were the Estates that their good faith should not be doubted, that they pledged the honour of the kingdom in proof of it.

From this point, the story of the Scots army merges into that of the civil wars of the period. And to relate it further would be to recapitulate what general histories of Scotland have already made more or less familiar to all.
