The winter months of 1190 and the spring of 1191 had been spent by them in very uneasy lodgings at Messina. Richard and Philip were, from the very first, jealous of one another. Richard was betrothed to Philip’s sister, and Philip suspected him of wishing to break off the engagement. Richard’s sister Johanna, the widow of William the Good, was still in Sicily. Richard wanted to get her and her fortune into his hands and out of the hands of Tancred, who, with a doubtful claim, had set himself up as King of Sicily against Henry of Hohenstaufen, who had married the late king’s aunt. Now, the Hohenstaufen and the French had always been allies; Richard, through his sister’s marriage with Henry the Lion, was closely connected with the Welfs, who had suffered forfeiture and banishment from the policy of Frederick Barbarossa. He was also naturally the ally of Tancred, who looked upon him as the head of Norman chivalry. Yet to secure his sister he found it necessary to force Tancred to terms. Whilst Tancred negotiated the people of Messina rose against the strangers; the strangers quarrelled among themselves; Philip planned treachery against Richard, and tried to draw Tancred into a conspiracy; Tancred informed Richard of the treachery. Matters were within a hair’s breadth of a battle between the crusading kings. Philip’s strength, however, was not equal to his spite, and the air gradually cleared. Tancred gave up the queen and her fortune, and arranged a marriage for one of his daughters with Arthur of Brittany, who was recognized as Richard’s heir. Soon after Queen Eleanor arrived at Naples with the lady Berengaria of Navarre in her company; whereupon, by the advice of Count Philip of Flanders, Philip released Richard from the promise to marry his sister; and at last, at the end of March, 1191, the French Crusaders sailed away to Acre. Richard followed in a few days; but a storm carrying part of his fleet to Cyprus, he found himself obliged to fight with Isaac Comnenus, the Emperor, and then to conquer and reform the island, where also he was married. After he reached Acre, where he arrived on June 8, he as well as Philip fell ill, and only after a delay of some weeks was able to take part in the siege. The town held out a little longer; but early in July surrendered, and gave the Christians once more a footing in the Holy Land. Immediately after the capture Philip started homewards, leaving his vow of pilgrimage unfulfilled. Richard remained to complete the conquest. [Sidenote: Richard’s campaigns in Palestine. ]
