The expedition started on the following morning, the 20th of November. It consisted of nearly six hundred natives belonging to the Napier tribes, the Mahia and Marsuwai tribes. The next day they came upon the rear-guard of the Hau-Hau tribes of Patutahi and shot two of them. Great quantities of booty which the Hau-Haus were unable to carry away were found there, together with the bodies of several friendly natives. The next day another encampment was come upon, and here the carts taken from the plundered farms were found. At dusk on the 23d the column came up with the main body of the enemy, who were encamped on the Te Karetua Creek.

A heavy fire was opened on both sides, and the natives then charged, but were driven back with a loss of five killed and twelve wounded. Mr. Atherton and Wilfrid, who were walking leisurely in the rear of the column when it came on the enemy, arrived too late to take any part in the fight. After the repulse the friendly natives took up a position on a ridge overlooking the Hau-Hau positions, and distant twelve hundred yards from it. Rifle-pits were dug, and for the next week firing was kept up by both sides, with occasional skirmishes as one party or the other tried to take the offensive, but neither cared to try a determined attack on the other.

The Hau-Haus had lost twenty men during the first day's fighting and suffered more in the distant firing, especially whenever they gathered as if for an attack, than did the friendlies. This was owing in no small degree to the accuracy of Mr. Atherton's fire. He had got some of the natives to dig a rifle-pit three or four hundred yards down the hill in front of their position, and here he and Wilfrid ensconced themselves every morning before daybreak, taking down with them their provisions for the day, and from this point they galled the Hau-Haus greatly with their fire. Wilfrid knew that his shooting could not be depended upon at this distance; but Mr. Atherton had been accustomed to fire at long ranges, and although at eight hundred yards his rifle was not accurate he did considerable execution, and so alarmed the Hau-Haus that they scarcely dared to move by daylight from one part of their intrenchment to the other. The friends always left their shelter and retired to camp as soon as the sun set.

The Hau-Haus were not, however, idle. A party of sixty men made a long circuit and came down in rear of the column, captured the depot at Patutahi with eight kegs of ammunition and a great quantity of provisions, and also seized a number of pack animals on the way up. On the 3d of December the force was strengthened by the arrival of the chiefs Rapata and Hotene, with three hundred and seventy men from Te Wairoa. These chiefly belonged to the Ngatiporou tribe, who were far better fighters than the Napier or Mahia men.

As soon as the reinforcements had arrived it was decided at once to dislodge the enemy from a hill of which they had possession, and then to make a general attack on the intrenchments. Forty men of the Wairoa tribe under Mr. Preece made a dashing attack on the hill, and just as they carried it Rapata sent a message to him to say that his tribesmen were annoyed by the enemy's shot falling into their camp, and were therefore determined to attack at once. That tribe sallying out, carried two of the enemy's outworks with a rush, and drove the Hau-Haus back to their last line of rifle-pits near the river. Here they were attacked by the Wairoa men on the left, Rapata in the centre, and the tribesmen from Napier on the right. The assailants carried the intrenchment and drove the Hau-Haus across the river, these suffering heavy loss from the firing of the left column, who from their position commanded the course of the stream.

Unfortunately this fire, though destructive to the enemy, was to a certain extent in their favour, for it prevented the close pursuit of Rapata's men. Thirty-four Hau-Haus, including three of their fighting chiefs, were found dead. Te Kooti himself had a narrow escape. He was still suffering from his wound in the ankle, and was carried up the bed of the creek on a woman's back. A great quantity of the loot taken from the settlers was recaptured, and many of the friendly natives held prisoners by the Hau-Haus escaped during the fight. Mr. Atherton and Wilfrid had joined Rapata's men in their charge, and after the fight was over the former said: "Well, Wilfrid, it is a satisfaction to have got some natives with us at last who will fight. It seemed at first as if all the plucky natives had joined the enemy; but Rapata's men are first-rate fellows, though I wish that they had rather an easier name, for Ngatiporou is a crack-jaw word to pronounce."

Unfortunately a quarrel arose after the battle between Rapata's men and the Napier tribesmen, and three hundred of the latter went off. The next morning Rapata and his tribe, with the remaining Wairoa men, marched out to attack the position the enemy occupied on the top of a hill two miles away. Mr. Preece led the advanced party, and found the defences consisted of two lines of strong earthworks extending across a flat shoulder, either end resting on a cliff. Mr. Preece halted his men until Rapata came up with the main body. Wilfrid and Mr. Atherton had attached themselves to the Ngatiporou. Just as they joined Mr. Preece one of the men fired off a gun, and the enemy answered with a heavy volley. Instantly a panic set in, and the whole force, with the exception of some sixteen or eighteen men, bolted. One of the chiefs under Mr. Preece followed and managed to stop them, and persuaded them to wait until Rapata could return to them. This they agreed to do, but refused positively to return to the attack.

Mr. Preece returned to Rapata, who was in a state of fury at the defection of his tribe. "We will go on and attack the place by ourselves," he said. "Perhaps the cowards will come up when they hear we are fighting." Mr. Preece at once agreed, and the party, consisting of the two leaders, Mr. Atherton and Wilfrid, and fourteen of Rapata's men, worked back through the low scrub until between twenty-five yards of the first line of earthworks, when they opened fire upon the enemy.

"This is rather close work, Wilfrid," Mr. Atherton said. "We have the best of it in some respects, because they cannot make out our position among the bushes, and they are obliged to stand up and show their heads above the parapet when they fire. We ought never to miss them at this distance, and we will soon teach them that it is fatal to pause a moment to take aim, so at the worst they will only blaze away at random."

For some time the fight continued, and then Rapata requested Mr. Preece to go down the hill and bring up some more men. Only nine men would follow Mr. Preece, and Rapata was so disgusted that he himself went down for some distance and managed to get thirty more. One of the men had brought a bill up with him, and with this shallow rifle-pits were dug among the bushes, affording a shelter to the men as they lay flat while loading. At three o'clock in the afternoon the chief called on his tribesmen to follow him, and, leaping up, they dashed at one of the outposts and carried it. A man took the news down the hill, and a chief and thirty more men came up and joined in the fight.
