ARGUMENT to Book IV.
The action of the poem being suspended by night, Ossian takes that opportunity to relate his own actions at the lake of Lego, and his courtship of Everallin, who was the mother of Oscar, and had died some time before the expedition of Fingal into Ireland. Her ghost appears to him, and tells him that Oscar, who had been sent, the beginning of the night, to observe the enemy, was engaged with an advanced party, and almost overpowered. Ossian relieves his son; and an alarm is given to Fingal of the approach of Swaran. The king rises, calls his army together, and, as he had promised the preceding night, devolves the command on Gaul the son of Morni, while he himself, after charging his sons to behave gallantly and defend his people, retires to a hill, from whence he could have a view of the battle. The battle joins; the poet relates Oscar's great actions. But when Oscar, in conjunction with his father, conquered in one wing, Gaul, who was attacked by Swaran in person, was on the point of retreating in the other. Fingal sends Ullin his bard to encourage him with a war song, but notwithstanding Swaran prevails; and Gaul and his army are obliged to give way. Fingal, descending from the hill, rallies them again: Swaran desists from the pursuit, possesses himself of a rising ground, restores the ranks, and waits the approach of Fingal. The king, having encouraged his men, gives the necessary orders, and renews the battle. Cuthullin, who, with his friend Connal, and Carril his bard, had retired to the cave of Tura, hearing the noise, came to the brow of the hill, which overlooked the field of battle, where he saw Fingal engaged with the enemy. He, being hindered by Connal from joining Fingal, who was himself upon the point of obtaining a complete victory, sends Carril to congratulate that hero on his success.
