In vain King James, who accompanied his army, formed it up in order of
battle within sight of the invaders' lines. Schomberg was not to be
tempted out, and, as the position appeared to be too strong to be
attacked, the Irish were forced to endeavour to reduce it by the slow
process of starvation. The English army was soon reduced to pitiable
straits--not from hunger, for they were able to obtain food from the
ships, but from disease. The situation of the camp was low and unhealthy.
Fever broke out, and swept away vast numbers of the men.

The Dutch and Enniskilleners suffered comparatively little--both were
accustomed to a damp climate. But of the English troops, nearly eight
thousand died in the two months that the blockade lasted. Had James
maintained his position, the whole of the army of Schomberg must have
perished; but, most unfortunately for his cause, he insisted on
personally conducting operations, and when complete success was in his
grasp he marched his army away, in the middle of November, to winter
quarters; thereby allowing Schomberg to move, with the eight thousand men
who remained to him, from the pest-stricken camp to healthier quarters.

The disgust, of those of James's officers who understood anything of war,
at this termination of the campaign was extreme. The men, indeed, were
eager to return to their homes, but would gladly have attempted an
assault on the English camp before doing so; and, as the defenders were
reduced to half their original strength, while most of the survivors were
weakened by disease, the attack would probably have been successful.
James himself was several times on the point of ordering an attack, but
his own vacillation of character was heightened by the conflicting
counsels of his generals, who seemed more bent on thwarting each other
than on gaining the cause for which they fought.
