The staff at headquarters was based on the model of that which had prevailed under Cromwell, though of course on a scale reduced to the minute proportions of the Army. The duties must, at first, have been within the scope of a very few officials, and it is probable that Monk required little assistance. There was, however, a commissary of the musters, to whom in 1664 a scoutmaster-general, or head of the intelligence department, was added. The business of foreign intelligence in all its branches, diplomatic, naval, and military, had been conducted with admirable efficiency during the Protectorate by the Secretary of State, John Thurloe, but Pepys remarked a sad falling away in this department after the Restoration, due, as he admits, to the scanty allowance of funds allotted to the service. Charles was not the man to face the difficulties of establishing a great administrative office on a sound basis. James, on the other hand, began to grapple with them very early after his accession. He strengthened the staff by the addition of adjutants and quartermasters-general of horse and foot, and strove hard to improve the efficiency of the office; but his time was too short and his distractions too manifold to permit him to do the work thoroughly. Had he reigned for ten years, his familiarity with the system of Louvois and his own administrative ability might have reduced our military system once for all to order. It is not too much to say that his expulsion was in this respect the greatest misfortune that ever befell the Army.
