They thought there would be wonder on Eochaid when he heard that news; but there was no wonder on him, for a dream had come to him in the night, and when he asked his Druids the meaning of the dream, it is what they said, that it would not be long till there would be a strong enemy coming against him.
Then King Eochaid took counsel with his chief advisers, and it is what they agreed, to send a good champion of their own to see the strangers and to speak with them. So they chose out Sreng, that was a great fighting man, and he rose up and took his strong red-brown shield, and his two thick-handled spears, and his sword, and his head-covering, and his thick iron club, and he set out from Teamhair, and went on towards the place the strangers were, at Magh Rein.
But before he reached it, the watchers of the Tuatha de Danaan got sight of him, and they sent out one of their own champions, Bres, with his shield and his sword and his two spears, to meet him and to talk with him.
So the two champions went one towards the other slowly, and keeping a good watch on one another, and wondering at one another's arms, till they came near enough for talking; and then they stopped, and each put his shield before his body and struck it hard into the ground, and they looked at one another over the rim. Bres was the first to speak, and when Sreng heard it was Irish he was talking, his own tongue, he was less uneasy, and they drew nearer, and asked questions as to one another's family and race.
And after a while they put their shields away, and it was what Sreng said, that he had raised his in dread of the thin, sharp spears Bres had in his hand. And Bres said he himself was in dread of the thick-handled spears he saw with Sreng, and he asked were all the arms of the Firbolgs of the same sort. And Sreng took off the tyings of his spears to show them better, and Bres wondered at them, being so strong and so heavy, and so sharp at the sides though they had no points. And Sreng told him the name of those spears was Craisech, and that they would break through shields and crush flesh and bones, so that their thrust was death or wounds that never healed. And then he looked at the sharp, thin, hard-pointed spears that were with Bres. And in the end they made an exchange of spears, the way the fighters on each side would see the weapons the others were used to. And it is the message Bres sent to the Firbolgs, that if they would give up one half of Ireland, his people would be content to take it in peace; but if they would not give up that much, there should be a battle. And he and Sreng said to one another that whatever might happen in the future, they themselves would be friends.
Sreng went back then to Teamhair and gave the message and showed the spear; and it is what he advised his people, to share the country and not to go into battle with a people that had weapons so much better than their own. But Eochaid and his chief men consulted together, and they said in the end: "We will not give up the half of the country to these strangers; for if we do," they said, "they will soon take the whole."
Now as to the Men of Dea, when Bres went back to them, and showed them the heavy spear, and told them of the strong, fierce man he had got it from, and how sturdy he was and well armed, they thought it likely there would soon be a battle. And they went back from where they were to a better place, farther west in Connacht, and there they settled themselves, and made walls and ditches on the plain of Magh Nia, where they had the great mountain, Belgata, in their rear. And while they were moving there and putting up their walls, three queens of them, Badb and Macha and the Morrigu, went to Teamhair where the Firbolgs were making their plans. And by the power of their enchantments they brought mists and clouds of darkness over the whole place, and they sent showers of fire and of blood over the people, the way they could not see or speak with one another through the length of three days. But at the end of that time, the three Druids of the Firbolgs, Cesarn and Gnathach and Ingnathach, broke the enchantment.
The Firbolgs gathered their men together then, and they came with their eleven battalions and took their stand at the eastern end of the plain of Magh Nia.
And Nuada, king of the Men of Dea, sent his poets to make the same offer he made before, to be content with the half of the country if it was given up to him. King Eochaid bade the poets to ask an answer of his chief men that were gathered there; and when they heard the offer they would not consent. So the messengers asked them when would they begin the battle. "We must have a delay," they said; "for we want time to put our spears and our armour in order, and to brighten our helmets and to sharpen our swords, and to have spears made like the ones you have. And as to yourselves," they said, "you will be wanting to have spears like our Craisechs made for you." So they agreed then to make a delay of a quarter of a year for preparation.
It was on a Midsummer day they began the battle. Three times nine hurlers of the Tuatha de Danaan went out against three times nine hurlers of the Firbolgs, and they were beaten, and every one of them was killed. And the king, Eochaid, sent a messenger to ask would they have the battle every day or every second day. And it is what Nuada answered that they would have it every day, but there should be just the same number of men fighting on each side. Eochaid agreed to that, but he was not well pleased, for there were more men of the Firbolgs than of the Men of Dea.
