So at length, when it was too late, all manner of energies were set to work. The city was refortified, a large store of arms was laid in, help was sent from Cyprus and the Islands of the Sea, until a force of nine hundred knights and eighteen thousand foot was within the walls. The care of the walls themselves was divided between Otho de Grandison, Henry, King of Cyprus, and the Master of the Teutonic Knights and the Masters of the Temple and the Hospital, with whom served the Masters of the Knights of the Sword and of the Knights of the Holy Ghost.

"These are the men," says one of the narratives of the survivors, "by whose prudence and counsel the city was to be governed. Had they been of one heart and mind, Heaven is our witness, Acre would still rejoice in the fulness of her strength." For alas, the old discord between the Templars and the Hospitallers had broken out afresh, and there was little hope of united action within the walls.

In the middle of March, the Saracens first appeared before Acre, "while making the earth to tremble at the march of their mailed men and to shake at the noise of their drums and cymbals; while the gilded shields of the soldiers flashed as the rays of the sun across the hills and their spearheads danced in the sunlight like stars in the midnight sky."

The din made before the walls was incessant. "They bellowed like bulls; they barked like dogs; they roared like lions; and ever, as is their wont, they drummed their huge tom-toms with their heavy-knotted sticks."

Then the war-engines were set up "which poured by day and by night a ceaseless hailstorm of stones upon the walls and city."

A partly successful sortie returned with some captives and the news that "the arrows were flying thicker than the flakes of snow in winter"; and on the Good Friday of the year 1291 Otho and the Templars planned a more united attack upon the Saracen camp. But this the Patriarch, acting on the advice of traitors, absolutely forbade, and so the last chance of saving the ill-fated city disappeared.

Many of the citizens and some of the fighting men now fled from Acre whenever they had the opportunity, but a considerable force yet remained, quite enough indeed to hold the city had they been content to work together. This, however, seemed impossible, and Khalil went boldly on to undermine the walls. The first direct assault was aimed at that section which was guarded by Henry of Cyprus, and only the nightfall prevented the Saracens from forcing an entrance. During the hours of darkness the King of Cyprus, with all his followers, crept to the harbour and secretly sailed away to his own island. And this he did, not so much in fear as in despair of ever accomplishing aught, when the petty quarrels and rivalries within the city left him without support.

This fatal policy of disunion was even more apparent during the last four days of that terrible siege. The Templars would not lift a hand to aid the Hospitallers; their bitter hostility made them more eager to fight each other than the infidel.

Meantime the Saracens had bridged the moat, broken through the outer walls, and driven the defenders to the inner part of the city. The captains, who were sitting in council, hastily donned their armour and rode forth into the midst of the panic-stricken crowd.
