Sarsfield
There is no evidence that Sarsfield was jealous that a Frenchman should be put over his head; this had, indeed, come to be part of the natural order in Ireland. But the final campaign had fully begun by May, when St. Ruth arrived at Limerick. Ginkel had moved on Ballymore, aiming at Athlone; and his first attempt had been ineffectual, ending in a withdrawal, dictated by the fear lest Sarsfield should cut his communications. The mind of William's party was by no means hopeful, as we find it reflected in the State Papers. But in May they report news of "great dissensions" among the Irish. St. Ruth on arriving had claimed to command on behalf not of James but of the King of France.14 This was in no way likely to shock Tyrconnell, who for long, had openly welcomed the idea of substituting King Louis for King James; but for a while Sarsfield refused to serve under the Frenchman on these terms. This may account for the "suspicious jealousy" (to quote Dr. Todhunter) with which St. Ruth regarded the man best fitted to help him.
The state of affairs in May before the serious fighting began may be inferred from one or two letters. On May 28th the Lords Justices wrote describing the commanding position held by the Irish army, which, stationed at Lough Rea, could move quickly to reinforce either Limerick
