But there was no paltering with the situation which arose in 724. Recourse was immediately had to the Fujiwara, whose position at the Imperial Court was paramount, and Umakai, grandson of the renowned Kamatari, set out at the head of thirty thousand men, levied from the eight Bands provinces, by which term Sagami, Musashi, Awa, Kazusa, Shimosa, Hitachi, Kotsuke, and Shimotsuke were designated. The expanded system of conscription established under the Daiho code was then in force, and thus a large body of troops could easily be assembled. Umakai's army did not experience any serious resistance. But neither did it achieve anything signal. Marching by two routes, it converged on the castle of Taga, a fortress just constructed by Ono Azumahito, the lord warden of the Eastern Marches. The plan pursued by the Yamato commanders was to build castles and barriers along the course of rivers giving access to the interior, as well as along the coast line. Taga Castle was the first of such works, and, by the year 767, the programme had been carried in Mutsu as far as the upper reaches of the Kitakami River,* and in Dewa as far as Akita.

*A monument still stands on the site of the old Taga Castle. It was put up in A.D. 762, and it records that the castle stood fifty miles from the island of Yezo.

History has nothing further to tell about the Yemishi until the year 774, when they again took up arms, captured one (Mono) of the Japanese forts and drove out its garrison. Again the eight Bando provinces were ordered to send levies, and at the head of the army thus raised a Japanese general penetrated far into Mutsu and destroyed the Yemishi's chief stronghold. This success was followed by an aggressive policy on the part of the lord-warden, Ki no Hirozumi. He extended the chain of forts to Kabe in Dewa, and to Isawa in Mutsu. This was in 780. But there ensued a strong movement of reprisal on the part of the Yemishi. Led by Iharu no Atamaro, they overwhelmed Hirozumi's army, killed the lord-warden himself, and pushed on to Taga Castle, which they burned, destroying vast stores of arms and provisions. It was precisely at this time that the State council, as related above, memorialized the Throne, denouncing the incompetency of the provincial conscripts and complaining that the provincial authorities, instead of training the soldiers, used them for forced labour. The overthrow of the army in Mutsu and the destruction of Taga Castle justified this memorial.

The Court appointed Fujiwara Tsugunawa to take command of a punitive expedition, and once again Bando levies converged on the site of the dismantled castle of Taga. But beyond that point no advance was essayed, in spite of bitter reproaches from Nara. "In summer," wrote the Emperor (Konin), "you plead that the grass is too dry; in winter you allege that bran is too scant. You discourse adroitly but you get no nearer to the foe." Konin's death followed shortly afterwards, but his successor, Kwammu, zealously undertook the pursuit of the campaign. Notice was sent (783) to the provincial authorities directing them to make preparations and to instruct the people that an armed expedition was inevitable. News had just been received of fresh outrages in Dewa. The Yemishi had completely dispersed and despoiled the inhabitants of two districts, so that it was found necessary to allot lands to them elsewhere and to erect houses for their shelter.

The Emperor said in his decree that the barbarian tribes, when pursued, fled like birds; when unmolested, gathered like ants; that the conscripts from the Bando provinces were reported to be weak and unfit for campaigning, and that those skilled in archery and physically robust stood aloof from military service, forgetting that they all owed a common duty to their country and their sovereign. Therefore, his Majesty directed that the sons and younger brothers of all local officials or provincial magnates should be examined with a view to the selection of those suited for military service, who should be enrolled and drilled, to the number of not less than five hundred and not more than two thousand per province according to its size. Thus, the eight Bando provinces must have furnished a force of from four to sixteen thousand men, all belonging to the aristocratic class. These formed the nucleus of the army. They were supplemented by 52,800 men, infantry and cavalry, collected from the provinces along the Eastern Sea (Tokai) and the Eastern Mountains (Tosan). so that the total force must have aggregated sixty thousand. The command in chief was conferred on Ki no Kosami, thirteenth in descent from the renowned Takenouchi-no-Sukune, who had been second in command of the Fujiwara Tsugunawa expedition nine years previously. A sword was conferred on him by the Emperor, and he received authority to act on his own discretion without seeking instructions from the Throne.

Meanwhile, the province of Mutsu had been ordered to send 35,000 koku (175,000 bushels) of hulled rice to Taga Castle, and the other provinces adjacent were required to store 23,000 koku (115,000 bushels) of hoshi-i (rice boiled and dried) and salt at the same place. The troops were to be massed at Taga, and all the provisions and munitions were collected there by April, 789. These figures are suggestive of the light in which the Government regarded the affair. Kosami moved out of Taga at the appointed time and pushed northward. But with every forward movement the difficulties multiplied. Snow in those regions lies many feet deep until the end of May, and the thaw ensuing brings down from the mountains heavy floods which convert the rivers into raging torrents and the roads into quagmires. On reaching the bank of the Koromo River, forty-five miles north of Taga, the troops halted. Their delay provoked much censure in the capital where the climatic conditions do not appear to have been fully understood or the transport difficulties appreciated. Urged by the Court to push on rapidly, Kosami resumed his march in June; failed to preserve efficient connexion between the parts of his army; had his van ambushed; fled precipitately himself, and suffered a heavy defeat, though only 2500 of his big army had come into action. His casualties were 25 killed, 245 wounded, and 1036 drowned. A truce was effected and the forces withdrew to Taga, while, as for Kosami, though he attempted to deceive the Court by a bombastic despatch, he was recalled and degraded together with all the senior officers of his army.

It would seem as though this disaster to one comparatively small section of a force aggregating from fifty to sixty thousand men need not have finally interrupted the campaign, especially when the enemy consisted of semi-civilized aborigines. The Government thought differently, however. There was no idea of abandoning the struggle, but the programme for its renewal assumed large dimensions, and events in the capital were not propitious for immediate action. The training of picked soldiers commenced at once, and the provision of arms and horses. Kosami's discomfiture took place in 789, and during the next two years orders were issued for the manufacture of 2000 suits of leather armour and 3000 of iron armour; the making of 34,500 arms, and the preparation of 1 10,000 bushels of hoshi-i. To the command-in-chief the Emperor (Kwammu) appointed Saka-no-ye no Tamuramaro.

This selection illustrates a conclusion already proved by the annals, namely, that racial prejudice had no weight in ancient Japan. For Tamuramaro was a direct descendant of that Achi no Omi who, as already related, crossed from China during the Han dynasty and became naturalized in Japan. His father, Karitamaro, distinguished himself by reporting the Dokyo intrigue, in the year 770, and received the post of chief of the palace guards, in which corps his son, Tamuramaro, thereafter served. Tradition has assigned supernatural capacities to Tamuramaro, and certainly in respect of personal prowess no less than strategical talent he was highly gifted. In June, 794, he invaded Mutsu at the head of a great army and, by a series of rapidly delivered blows, effectually crushed the aborigines, taking 457 heads, 100 prisoners, and 85 horses, and destroying the strongholds of 75 tribes. Thereafter, until the year of his death (811), he effectually held in check the spirit of revolt, crushing two other insurrections—in 801 and 804—and virtually annihilating the insurgents. He transferred the garrison headquarters from Taga to Isawa, where he erected a castle, organizing a body of four thousand militia (tonden-hei) to guard it; and in the following year (803), he built the castle of Shiba at a point still further north.

NATIONALITY OF THE INSURGENTS

Annals of historical repute are confined to the above account. There is, however, one unexplained feature, which reveals itself to even a casual reader. In their early opposition to Yamato aggression, the Yemishi—or Ainu, or Yezo, by whatever name they be called—displayed no fighting qualities that could be called formidable. Yet now, in the eighth century, they suddenly show themselves men of such prowess that the task of subduing them taxes the resources of the Yamato to the fullest. Some annalists are disposed to seek an explanation of this discrepancy in climatic and topographical difficulties. Kosami, in his despatch referring to the Koromo-gawa campaign, explains that 12,440 men had to be constantly employed in transporting provisions and that the quantity carried by them in twenty-four days did not exceed eleven days' rations for the troops. The hardship of campaigning in a country where means of communication were so defective is easily conjectured, and it has also to be noted that during only a brief period in summer did the climate of Mutsu permit taking the field. But these conditions existed equally in the eras of Yamato-dake and Hirafu. Whatever obstacles they presented in the eighth century must have been equally potent in the second and in the seventh.
