It lacked two hours before the dawn on this sultry night early in September. The crescent moon had long ago sunk behind a bank of clouds in the west, and not a sound stirred the low-lying land around the besieged city. To the south the bivouac fires of Alva's camp had died out one by one, and here the measured tread of the sentinels on their beat alone broke the silence of the night. To the north, where valorous Orange with a handful of men--undisciplined, unpaid and rebellious--vainly tried to provoke his powerful foe into a pitched battle, relying on God for the result, there was greater silence still. The sentinels--wearied and indifferent--had dropped to sleep at their post: the troops, already mutinous, only held to their duty by the powerful personality of the Prince, slept as soundly as total indifference to the cause for which they were paid to fight could possibly allow. In his tent even Orange--tired out with ceaseless watching--had gone to rest. His guards were in a profound sleep. Then it was that from the south there came a stir, and from Alva's entrenchments waves of something alive that breathed in the darkness of the night were set in motion, like when the sea rolls inwards to the shore. Whispered words set this living mass on its way, and anon it was crawling along--swiftly and silently--more silently than incoming waves on a flat shore--on and on, always northwards in the direction of the Prince of Orange's camp, like some gigantic snake that creeps with belly close to the ground. "Don Ramon," whispered a voice in the darkness, "let Captain Romero deal with the sentinels and lead the surprise attack, whilst you yourself make straight for the Prince's tent; overpower his guard first, then seize his person. Two hundred ducats will be your reward, remember, if you bring Orange back here--a prisoner--and a ducat for each of your men." These were the orders and don Ramon de Linea sped forward with six hundred arquebusiers--all picked men--they wore their shirts over their armour, so that in the melee which was to come they might recognise one another in the gloom. Less than a league of flat pasture land lay between Alva's entrenchments at St. Florian near the gates of beleaguered Mons, and Orange's camp at Hermigny. But at St. Florian men stirred and planned and threatened, whilst at Hermigny even the sentinels slept. Noble-hearted Orange had raised the standard of revolt against the most execrable oppression of an entire people which the world has ever known--and he could not get more than a handful of patriots to fight for their own freedom against the tyranny and the might of Spain, whilst mercenary troops were left to guard the precious life of the indomitable champion of religious and civil liberties."
