The Indian reinforcements continued to increase. Miantonomo brought two hundred warriors, and other allied tribes joined them on their march, until the number of native auxiliaries amounted to five hundred. In these Mason placed little confidence, and would gladly have awaited the arrival of the forty men from Plymouth, who were already at Providence on their way to join him. But his men were eager to attack the savages, and the Indians taunted him with cowardice for desiring to delay the conflict; and he was forced to advance at once. The great strength of the Pequodees consisted in two large forts, in one of which the redoubted Chief, Sassacus, himself commanded. The other was situated on the banks of the Mystic, an inconsiderable river that runs parallel to the Connecticut. These Indian forts or castles consisted of wooden palisades, thirty or forty feet high, generally erected on an elevated situation, and enclosing a space sufficiently large to contain a considerable number of wigwams for the aged men--or whiteheads--and the women and children. These two fortresses were the pride and the confidence of the Pequodees, who believed them to be invulnerable; as, indeed, they had hitherto found them to the assaults of their own countrymen. And the other Indian tribes appeared to hold them in the same estimation; for when they found that it was Mason's intention to march directly to the fort on the Mystic, their courage failed completely. They were only accustomed to the Indian mode of warfare, which consists in secret attacks and cunning stratagems; and the idea of braving the terrible Pequodees in their strongholds, overpowered their resolution. The very warriors who, only the day before, had boasted of their deeds, now were crest-fallen, and cried out, 'Sassacus is a God; he is invincible!' and they deserted in troops, and returned to their own dwellings. Thus the English found themselves deprived of at least a hundred of their Narragansett allies. The rest remained with them, as did also the Mohicans; but their fear of the Pequodees was so great, that Mason could only employ them as a sort of rear-guard. Meanwhile, these haughty Indians were exulting in their supposed security, and indulging in songs and feasting. They believed that the English were terrified at their strength and reputed numbers, and had fled from the intended place of landing in Pequod harbor in fear, and had abandoned their enterprise altogether. They, therefore, amused themselves with fishing in the bay; and then inviting their allies to join their revels, they passed the night in vaunting of their own great actions, and defying the cowardly whites.
