Every Kayan household possesses, beside the many smaller boats, one or more boats especially designed for use in war. A typical war-boat is about 100 feet in length, from six to seven feet wide in its middle part, and tapers to a width of about three and a half feet at bow and stern. In some cases the length of the war-boat, which is always made from a single log, is as much as 145 feet in length (Pl. 96), but so large a boat is unwieldy in use, and its construction costs an excessive amount of labour. The ordinary war-boat carries from sixty to seventy men seated two abreast on the cross-benches. It is steered by the paddles of the two bow-men and the four next the stern. One of these war-boats, manned by sixty or seventy paddlers, can maintain a pace about equal to that of our University racing eights.[57]
War is only undertaken after formal consultation and many discussions between the chief or chiefs and all the leading men. If the village primarily concerned does not feel itself strong enough to achieve its ends, it will seek the help of some neighbouring village, usually, but not always one of its own tribe. The discussion may be renewed day after day for some little time, before the decision to fight is taken and the time for the expedition is fixed.
The next step is to seek favourable omens, and two men are told off for this work. They repair to some spot in the jungle, or more commonly on the bank of the river, where they build a small hut; they adorn it by fraying the poles of its framework, and so secure themselves against interruptions by passing acquaintances. The sight or sound of certain birds and beasts is favourable, of others unfavourable; but the favourable creatures must be observed in a certain order, if the omens are to be entirely satisfactory. If very bad omens are observed, the men return home to report the fact, and will make another attempt after a few days. If the omens are of mixed character, they will persist for some time, hoping to get a sufficient number of good omens to counteract or nullify the bad. When seeking for their place of observation, their choice is determined by seeing a spider-hunter (ARACHNOTHERA) flying across the river, chirping as it flies. When this is seen they stop the boat, calling out to the bird, "O friend ISIT, protect us and give us success." One of the men lands on the bank, hews out a pole about eight feet long, cuts upon it bunches of shavings without detaching (Pl. 97) them from the pole, and thrusts one end of it into the ground so that it remains sloping towards the abode of the foe. While this is being done on the bank, fire of some sort (if only a cigarette) is lighted in the boat, and the position is explained more fully to the bird, but without any mention of the name of the enemy. The observers then erect a hut near the omen-pole for their shelter, and pass the night there before looking out for the omen-bird next desired. This is the trogan (HARPACTES DUVAUCELII), which has a peculiar soft trilling note and a brilliant red chest. When this bird appears, it is addressed in the same way as the spider-hunter; and this second step of the process is also marked by a feathered stick thrust into the ground before the hut. Then they spend another night in the hut hoping for significant dreams. To dream of abundance of fruit (which symbolises heads) is favourable; any dream of a disagreeable or fearful situation is unfavourable. After a favourable dream comes the most important stage of the business, the observation of the hawks. They look for LAKI NEHO from the door of their hut about nine o'clock in the morning. As soon as a hawk is seen, they light a fire and call on him to go to the left, waving a feathered stick in that direction, and, shouting at the top of his voice, one of them pours out a torrent of words addressed to the hawk. If he goes out of sight towards the right, they console themselves by remarking that he is one of low degree, and they sit down to wait for another. If two hawks are seen to fight in the air, that foretells much bloodshed. They are not satisfied until they see a hawk sail far away out of sight towards the left. Then a break is made; after which they observe the hawks again, until they see one sail out of sight towards the right. If all this is accomplished without the intervention of unfavourable omens, they return home to report progress; but immediately return to the hut and remain there. Then for one, two, or even three days, all the men of the house stay at home quietly, busying themselves in preparing boats and weapons. The chief, or some deputy, then performs the rites before the altar-post of the war-god that stands before the house in the way described in Chap. XV. The omens given by the hawks on this occasion are guarantees for the safety of the house and those left in it, and against accidents and sickness incidental to the journey; they have no reference to the actual fighting.[58] All the men of the war-party then proceed in their war-boats to the spot where the war-omens have been observed, and camp round about it in roughly built huts. Here they will remain at least two days, establishing their connection with the favourable omen-birds. From this encampment they may not return to the house, and, if they are expecting a party of allies, they may await them here. By this time the war-fever is raging among them, and rumours of the preparations of the enemy are circulating. Spies or scouts may be sent out to seek information about the enemy; but usually such information is sought from the liver of a pig with the customary ceremony. A sharp ridge on the liver dividing their own region from that of the enemy is unfavourable, a low soft ridge is favourable.
From the moment of leaving the village the men of the war-party must observe many tabus until their return home. They may not eat the head of a fish; they must use only their home-made earthen pots; fire must be made only by friction (see Pl. 89); they must not smoke; boys may not lie down, but must sleep sitting. The people who remain at home are not expected to observe these tabus; they may go to the farms, but must keep quiet, and undertake nothing outside the ordinary routine.
If the object of the attack is a village in their own river, the expedition paddles steadily day after day until it reaches the mouth of some small stream at a distance of some miles from the enemy's village. Forcing their boats some two or three miles up this stream they make a camp. Here two solid platforms are built about twenty feet apart, and a large beam is laid from one to the other. The chiefs and principal men take their seats on the platforms, and then every man of the party in turn approaches this beam, the fighting leader, who is usually not one of the chiefs, coming first. If he is willing to go through with the business, I.E. to take part in the attack, he slashes a chip from the beam with his PARANG and passes under it. On the far side of the beam stands a chief holding a large frond of fern, and, as each man passes under, he gives him a bit of the leaf, while an assistant cuts a notch on a tally-stick for each volunteer. If for any reason any man is reluctant to go farther, he states his excuse, perhaps a bad dream or illness, or sore feet, and returns to the boats, amid the jeers of those who have passed the ordeal, to form one of a party to be left in charge of the camp and boats.
Next, all the left-handed men are sorted out to form a party whose special duty is to ambush the enemy, if possible, at some favourable spot. These are known as the hornets (SINGAT). If any swampy ground or other obstruction intervenes between their camp and the enemy's village, a path is made through or over it to facilitate retreat to the boats. A password is agreed upon, which serves as a means of making members of the party known to one another upon any chance meeting in the dark.
Scouts are sent out at dusk and, if their reports are favourable, the attack is made just before dawn. About half the warriors are provided with large bundles of dry shavings, and some will carry torches. When the attacking party has quietly surrounded the house or houses, the bundles of shavings are ignited, and their bearers run in and throw them under the house among the timbers on which it is supported. Then ensues a scene of wild confusion. The calm stillness of the tropical dawn is broken by the deep war-chorus of the attacking party, by the shouts and screams of the people of the house suddenly roused from sleep, by the cries and squeals of the frightened animals beneath the house, and the beating of the alarm signal on the TAWAK. If the house is ignited, the encircling assailants strive to intercept the fleeing inhabitants. These, if the flames do not drive them out before they have time to take any concerted measures, will hurl their javelins and discharge their firearms (if they have any) at their assailants; then they will descend, bringing the women and children with them, and make a desperate attempt to cut their way through and escape to the jungle or, sometimes, to their boats. Kayans conducting a successful attack of this kind will make as many prisoners as possible, and will as a rule kill only those men who make desperate resistance, though occasionally others, even women and children, may be wantonly killed in the excitement of the moment. It is not unusual in the case of an able-bodied man who has surrendered, but shown signs of attempting to escape or of renewing his resistance, to deal him a heavy blow on the knee-cap, and so render him lame for some time. It usually happens that the greater part of the fugitives escape into the jungle; and they are not pursued far, if the victors have secured a few heads and a few prisoners. The head is hacked off at once from the body of any one of the foe who falls in the fight; the trunk is left lying where it fell. If any of the assailants are killed in the course of the fray, their heads are not taken by their friends, and their corpses are left upon the field covered with boughs, or at most, in the case of chiefs, are dragged into the jungle and covered up with boughs and twigs, in order to prevent their heads being taken by the enemy. If any of the enemy remain so badly wounded that they are not likely to recover, their heads are taken; and if no other heads have been secured, the head of one of the more seriously wounded captives is taken, or of one who is deformed or incapacitated in any way. If a captive dies of his wounds his head is taken; but it is a rare exception for Kayans to kill any of their captives after the short excitement of the battle is over. The attacking party, even though it has gained a decisive victory, usually returns with all speed, but in good order, to its boats, carrying with it through the jungle all the loot that is not too cumbersome for rapid portage, especially old beads, gongs, and brass-ware; for they are always in danger of being cut off by a party of their enemies, rallied and reinforced by parties from neighbouring friendly villages. Still more are they liable to be pursued and cut off, if the attack on the village has failed through the defenders having been warned; for an attack upon a strong house or village has little chance of success if the defenders are prepared for and expecting it. The pursuit of the retreating party may be kept up throughout one or two days, and, if the pursuers come up with them, a brisk and bloody battle is the natural outcome; and it is under these circumstances that the most severe fighting takes place. But here again it is seldom that any large proportion of either party is slain; for the dense jungle everywhere offers abundant opportunities of concealment to those who condescend to seek its shelter, and there are few, even among the Kayans and Kenyahs, who will fight to the bitter end, if the alternative of flight is open to them.
A successful war-party returning home makes no secret of its success. The boats are decorated with palm leaves (DAUN ISANG), and a triumphal chorus is raised from time to time, especially on passing villages. As the villagers come out to gaze on them, those who have taken heads stand up in the boats. The heads, slightly roasted, are wrapped up in palm leaves and placed in baskets in the stern of the boat. If the return home involves a journey of several days, the victors will, if possible, pass the nights in the houses of friendly villages, where they are made much of, especially those who have taken heads; and on these occasions the glamour of victory is apt to turn the heads of some of the women and to break down the reserve that modesty normally imposes upon them.
On approaching their own village, whither the rumour of their success usually precedes them, the war-party is received with loud acclamations, the people coming down to the riverside to receive them. Before they ascend to the house, the heads have to be safely lodged in a small hut specially built for their reception; and the young boys are brought down to go through their first initiation in the arts of war. Each child is made to hold a sword and, with the assistance of some aged warrior, to strike a blow at one of the newly captured heads. The older boys, some nine or ten years of age, who are ripe for their second participation in mock warfare, also strike at a head in a similar way, but engage also in mimic battles with one another, using wooden swords and spears, and, curiously enough, small roughly made bows and arrows.[59] It is customary for the victorious warriors to spend the first night after their return encamped before the house. A strip of green DAUN ISANG is tied about the left wrist of each man who has taken part in the expedition, and also of each of the young boys. Those who have taken heads adorn also their war-caps with the same leaf and with feathered sticks. On the following day a tall post of bamboo (BALAWING) is erected near the figure of the war-god. It is covered with frayed palm leaves (DAUN ISANG), and from its tip a single head, also wrapped in leaves, is suspended by a long cord (Pl. 66). Before the altar-post of the war-god several shorter thicker posts are erected, and to each of these two or three small pieces of human flesh, brought home from the corpses of the slain enemies for this purpose, are fastened with skewers. These pieces of flesh seem to be thank-offerings to the hawks to whom the success is largely attributed. These bits of flesh are dried over a fire at the first opportunity on the return journey, in order to preserve them.[60]
As soon as the news of the taking of heads reaches the house, the people go out of mourning, I.E. they shave the parts of the scalp surrounding the crown and pull out eyebrows and eyelashes (which have been allowed to grow during mourning); they put off their bark-cloth garments and resume their cotton-cloths and ornaments.
