At length the Emperor set out from Constantinople after taking leave of his family, to visit a strong Castle he had in Spain.—While he was absent, Brandiser brother to Feragus invaded the Empire with a very great army, and at length besieged Constantinople, where lay Valentine and Orson, the Green Knight and all the Ladies.
Valentine seeing the condition they all were in, resolved to give Brandiser battle, and thereupon divided his army into ten battalions, commanded by ten Knights, and sallying out of the City, began to fight with the Saracens, who were drawn up in readiness to receive them.
In the mean time the Emperor was at sea, returning homeward, and in his way he met a fleet going to the assistance of Brandiser, which bore upon him with full sails: whereupon exhorting his companions to behave like men, they made ready to receive them; and after a most bloody and obstinate battle, the Emperor got the victory, having slain many of the Pagans, and dispersed all their ships.
After this victory the Emperor commanded his men to put on the Arms of the Vanquished, as he did himself, thinking thereby the better to fall upon the beseigers, his enemies; but the Stratagem proved most fatal to him, as we shall hereafter find.
All this while the Christians and Valentine bravely encountered Brandiser and his men before the Walls of Constantinople, sometimes getting, and sometimes losing ground; but at length Valentine came to the standard of Brandiser, where an Indian King run against him with great force, but Valentine avoided him, struck him with such fury as cleft him down the Middle. On the other hand Orson and the Green Knight were not idle, but with their brandished swords cut themselves a passage quite through the Pagan army, destroying all that opposed them.
Soon after news came that a mighty fleet of Saracens were entering the harbour; whereupon Valentine judged it necessary to go thither, and oppose their landing, but it proved fatal; for in his fleet was the Emperor his father, who being clad in Saracen armour, Valentine by mistake ran him quite through the body with his spear; which when he knew, he was going to kill himself, had not his brother and the Green Knight prevented him; but getting an horse with an intent to lose his life, he rushed into the midst of the enemy, overthrew all that opposed him, till he came to the Giant Brandiser, who when he saw Valentine, encountered him so fiercely, that both fell to the ground; but Valentine recovering, gave him a stab which sent him to hell, to see his false prophet Mahomet—
The Pagans seeing their King dead, threw down their arms and run, and the Christians pursued them with a mighty slaughter—At last the pursuit being over, they returned to Constantinople and Orson acquainted the Empress of the death of his father, but concealed by whom it was done.
