One of the first measures of the national council, when war is resolved upon, is to dispatch messengers to the confederate tribes, and even to the Indians who live under the Spanish government, to summon them to make common cause with their countrymen. The credentials of these messengers are some small arrows tied together by a red string, the symbol of blood. But if hostilities have been already commenced, the finger of a slain enemy accompanies the arrows. This embassy is called _pulchitum_, which signifies to run the arrow, and the messengers are called _guerquenis_. The toqui or military dictator directs what number of soldiers is to be furnished by each Uthal-mapu or principality. The particular toquis regulate the contingencies of the Apo-ulmens; and these last apportion these among the several Ulmens of their provinces. The army of the state usually consists of five or six thousand men; besides which, a body of reserve is always in readiness for particular occasions, or to replace those who may be killed in battle. Before taking the field, the general assigns three days for consultation with his principal officers, during which the plan of the campaign is maturely deliberated upon, and every one has liberty to offer his opinion: But the general finally settles the plan of warfare in secret consultation, with his principal officers. After all is agreed upon, the army commences its march to the sound of drums, and is always preceded by several advanced parties, to guard against surprise. During the march, the infantry as well as the cavalry are on horseback; but on coming to action, the infantry dismounts and is regularly marshalled in companies and battalions. All the soldiers have to provide their own horses arms and provisions; and as all are liable to military service, no one has to contribute towards the supply of the army. Their provisions consist chiefly in a small sack of parched meal, which each soldier carries on his horse; and which, diluted with water, serves them as food till they can live at free quarters in the enemys country. Being thus unencumbered with baggage, they are able to move with astonishing celerity, either to attack or to retreat as may be necessary. They are extremely vigilant when in presence of the enemy, encamping always in secure and advantageous situations, strengthening their posts with entrenchments, and placing sentinels on all sides, every soldier being obliged during the night to keep a fire burning in front of his tent. When necessary they protect their posts and encampments with deep trenches, guarded by abatis or hedges of spinous or thorny trees, and strew calthrops at all the avenues to repress attacks from the cavalry of the enemy. In short there are few military stratagems with which they are unacquainted, and are wonderfully expert in tactics [53].
