f, Goignies, rode to and fro, as the army proceeded,
each attended by his staff. The troops of Don John broke up from before
Namur with the earliest dawn, and marched in pursuit of the retiring foe.
In front was nearly the whole of the cavalry-carabineers, lancers, and
heavy dragoons. The centre, arranged in two squares, consisted chiefly of
Spanish infantry, with a lesser number of Germans. In the rear came the
Walloons, marching also in a square, and protecting the baggage and
ammunition. Charles Mansfeld had been left behind with a reserved force,
stationed on the Meuse; Ottavio Gonzaga commanded in front, Ernest
Mansfeld brought up the rear; while in the centre rode Don John himself,
attended by the Prince of Parma. Over his head streamed the
crucifix-emblazoned banner, with its memorable inscription--In hoc signo
vici Turcos, in hoc Haereticos vincam.

Small detachments of cavalry had been sent forward; under Olivera and
Acosta, to scour the roads and forests, and to disturb all ambuscades
which might have been prepared. From some stragglers captured by these
officers, the plans of the retreating generals were learned. The winter's
day was not far advanced, when the rearward columns of the states' army
were descried in the distance. Don John, making a selection of some six
hundred cavalry, all picked men, with a thousand infantry, divided the
whole into two bodies, which he placed under command of Gonzaga and the
famous old Christopher Mondragon. These officers received orders to hang
on the rear of the enemy, to harass him, and to do him all possible
damage consistent with the possibility of avoiding a general engagement,
until the main army under Parma and Don John should arrive. The orders
were at first strictly obeyed. As the skirmishing grew hotter, however,
Goazaga observed that a spirited cavalry officer, named Perotti, had
already advanced, with a handful of men, much further within the reach of
the hostile forces than was deemed expedient. He sent hastily to recal
the too eager chieftain. The order, delivered in a tone more peremptory
than agreeable, was flatly disobeyed. "Tell Ottavio Gonzaga," said
Perotti, "that I never yet turned my back on the enemy, nor shall I now
begin. Moreover, were I ever so much inclined to do so, retreat is
impossible." The retiring army was then proceeding along the borders of a
deep ravine, filled with mire and water, and as broad and more dangerous
than a river. In the midst
