So what if Philip dosen't get dysentery, and stays with the Crusade?Wikipedia said:By the time Acre surrendered on July 12, Philip was severely ill with dysentery and had little more interest in further crusading. He decided to return to France, a decision that displeased King Richard I, who said, "It is a shame and a disgrace on my lord if he goes away without having finished the business that brought him hither. But still, if he finds himself in bad health, or is afraid lest he should die here, his will be done." So on July 31, 1191 the French army of 10,000 men (along with 5,000 silver marks to pay the soldiers) remained in Outremer under the command of Hugh III, duke of Burgundy. Philip and his cousin Peter of Courtenay, count of Nevers, made their way to Genoa and from there returned to France. This decision to return was also fuelled by the realization that with Richard campaigning in the Holy Land, English possessions in northern France (Normandy) would be open for attack. After Richard's delayed return home after the Third Crusade, war between England and France would ensue over possession of English-controlled territories in modern-day France.
