This was an open defiance of English power, and he prepared to abide the consequences.

He thought the opportunity a favourable one to recover the supremacy of his ancestors over the O'Donels.

He accordingly mustered a numerous army, and marched into Tyrconnel, where he was joined by Hugh O'Donel, brother of Calvagh, the chief, with other disaffected persons of the same clan.

O'Donel had recourse to stratagem.

Having caused his cattle to be driven out of harm's way, he sent a spy into the enemy's camp, who mixed with the soldiers, and returning undiscovered, he undertook to guide O'Donel's army to O'Neill's tent, which was distinguished by a great watch-fire, and guarded by six galloglasses on one side and as many Scots on the other.
