fortified = to make stronger

The inhabitants have fortified the fountain-head of this river, which springs a little without the towns; that so, if they should happen to be besieged, the enemy might not be able to stop or divert the course of the water, nor poison it; from thence it is carried, in earthen pipes, to the lower streets.†

Their bodies are vigorous and lively; and though they are but of a middle stature, and have neither the fruitfullest soil nor the purest air in the world; yet they fortify themselves so well, by their temperate course of life, against the unhealthiness of their air, and by their industry they so cultivate their soil, that there is nowhere to be seen a greater increase, both of corn and cattle, nor are there anywhere healthier men and freer from diseases; for one may there see reduced to practice not only all the art that the husbandman employs in manuring and improving an ill soil, but whole woods plucked up by the roots, and in other places new ones planted, where there were none before.†

They fortify their camps with a deep and large trench; and throw up the earth that is dug out of it for a wall; nor do they employ only their slaves in this, but the whole army works at it, except those that are then upon the guard; so that when so many hands are at work, a great line and a strong fortification is finished in so short a time that it is scarce credible.†

but if their government is the best, and their religion the truest, then they pray that He may fortify them in it, and bring all the world both to the same rules of life, and to the same opinions concerning Himself, unless, according to the unsearchableness of His mind, He is pleased with a variety of religions.†
