With much grumbling the Scots marched as far as Ipswich on their way to their port of embarkation, and then, at a signal from some Jacobite officers, they broke into mutiny, seized four cannon, and, turning northward, advanced by forced marches towards Scotland. The alarm in London was great. "If you let this evil spread," said Colonel Birch, an old officer of Cromwell's day, "you will have an army upon you in a few days." William at once detached Ginkell, one of his best officers, with a large force in pursuit; the mutineers were overtaken near Sleaford, and, finding resistance hopeless, laid down their arms. William, selecting a few of the ringleaders only for punishment, ordered the rest of the regiment to return to its duty, and the Royal Scots sailed quietly away to the Maas. There the men deserted by scores, and even by hundreds,[228] but recruits were found, as good as they, to uphold the ancient reputation of the regiment. Meanwhile good came out of evil, for the mutiny frightened the House of Commons not only into paying the expenses of William's expedition, but into passing the first Mutiny Act. It is true that the Act was passed for six months only, and that it provided for no more than the punishment of mutiny and desertion; but it recognised at least that military crime cannot be adequately checked by civil law, and it gave the Army more or less of a statutory right to exist. But readers should be warned once for all against the common fallacy that the existence of the Army ever depended on the passing of the annual Mutiny Act. The statute simply empowered the King to deal with certain military crimes for which the civil law made no provision. It made a great parade of the statement that the raising or keeping of a standing army in time of peace is against law, but the standing army was in existence for nearly thirty years before the Mutiny Act was passed, and continued to exist, as will be seen, for two short but distinct periods between 1689 and 1701 without the help of any Mutiny Act whatever. If, therefore, the keeping of a standing army in time of peace be against the law, it can only be said that during those periods Parliament deliberately voted money for the violation of the law, as indeed it is always prepared to do when convenient to itself. The Mutiny Act was not a protection to liberty; Parliament for the present reserved for itself no check on the military code that might be framed by the King; and the Act was therefore rather a powerful weapon placed in the hands of the sovereign. Nevertheless, the passing of the Mutiny Act remains always an incident of the first importance in the history of the Army, and the story of its origin is typical of the attitude of Parliament towards that long-suffering body. Every concession, nay, every commonest requirement, must be wrung from it by the pressure of fear.
