And when he got near the bank of the river, as he was feeling his way round a marsh, partly overflowed, seeking some path by which to cross it, his horse suddenly stumbled in some soft and sticky place, and he was thrown down, but though he was fat and heavy, he without delay reached the shelter of a hill in the neighbourhood; there he was recognized (for indeed he could not conceal who he was, being betrayed by the greatness of his former fortune): and immediately a squadron of cavalry came up at full gallop with its tribune, and cautiously surrounded the wooded mound; though they feared to enter the thicket lest they should fall into any ambuscade concealed among the trees.
