He became afflicted with one of those slow and wasting fevers peculiar to Asia, and in despite of his great strength and still greater courage, grew first unfit to mount on horseback, and then unable to attend the councils of war which were from time to time held by the Crusaders.

It was difficult to say whether this state of personal inactivity was rendered more galling or more endurable to the English monarch by the resolution of the council to engage in a truce of thirty days with the Sultan Saladin; for on the one hand, if he was incensed at the delay which this interposed to the progress of the great enterprise, he was, on the other, somewhat consoled by knowing that others were not acquiring laurels while he remained inactive upon a sick-bed.
That, however, which Coeur de Lion could least excuse was the general inactivity which prevailed in the camp of the Crusaders so soon as his illness assumed a serious aspect; and the reports which he extracted from his unwilling attendants gave him to understand that the hopes of the host had abated in proportion to his illness, and that the interval of truce was employed, not in recruiting their numbers, reanimating their courage, fostering their spirit of conquest, and preparing for a speedy and determined advance upon the Holy City, which was the object of their expedition, but in securing the camp occupied by their diminished followers with trenches, palisades, and other fortifications, as if preparing rather to repel an attack from a powerful enemy so soon as hostilities should recommence, than to assume the proud character of conquerors and assailants.
The English king chafed under these reports, like the imprisoned lion viewing his prey from the iron barriers of his cage.

Naturally rash and impetuous, the irritability of his temper preyed on itself.

He was dreaded by his attendants and even the medical assistants feared to assume the necessary authority which a physician, to do justice to his patient, must needs exercise over him.

One faithful baron, who, perhaps, from the congenial nature of his disposition, was devoutly attached to the King's person, dared alone to come between the dragon and his wrath, and quietly, but firmly, maintained a control which no other dared assume over the dangerous invalid, and which Thomas de Multon only exercised because he esteemed his sovereign's life and honour more than he did the degree of favour which he might lose, or even the risk which he might incur, in nursing a patient so intractable, and whose displeasure was so perilous.
Sir Thomas was the Lord of Gilsland, in Cumberland, and in an age when surnames and titles were not distinctly attached, as now, to the individuals who bore them, he was called by the Normans the Lord de Vaux; and in English by the Saxons, who clung to their native language, and were proud of the share of Saxon blood in this renowned warrior's veins, he was termed Thomas, or, more familiarly, Thom of the Gills, or Narrow Valleys, from which his extensive domains derived their well-known appellation.
This chief had been exercised in almost all the wars, whether waged betwixt England and Scotland, or amongst the various domestic factions which then tore the former country asunder, and in all had been distinguished, as well from his military conduct as his personal prowess.
