beneath the Porcupine.
It did its work effectively, and the 29 May assailants did theirs no less
admirably, crowding into the breach with headlong ferocity, and after a
long and sanguinary struggle with immense lose on both sides, carrying
the precious and long-coveted work by storm. Inch by inch the defenders
were thus slowly forced back toward their new entrenchment. On the same
day, however, they inflicted a most bloody defeat upon the enemy in an
attempt to carry the great Polder. He withdrew, leaving heaps of slain,
so that the account current for the day would have balanced itself, but
that the Porcupine, having changed hands, now bristled most formidably
against its ancient masters. The daily 'slaughter had become sickening to
behold. There were three thousand effective men in the garrison. More
could have been sent in to supply the steady depletion in the ranks, but
there was no room for more. There was scarce space enough for the living
to stand to their work, or for the dead to lie in their graves. And this
was an advantage which could not fail to tell. Of necessity the besiegers
would always very far outnumber the garrison, so that the final success
of their repeated assaults became daily more and more possible.

Yet on the 2nd June the enemy met not only with another signal defeat,
but also with a most bitter surprise. On that day the mine which he had
been so long and so laboriously constructing beneath the great Polder
Bulwark was sprung with magnificent effect. A breach, forty feet wide,
was made in this last stronghold of the old defences, and the soldiers
leaped into the crater almost before it had ceased to blaze, expecting by
one decisive storm to make themselves masters at last of all the
fortifications, and therefore of the town itself. But as emerging from
the mine, they sprang exulting upon the shattered bulwark, a
transformation more like a sudden change in some holiday pantomime than a
new fact in this three years' most tragic siege presented itself to their
astonished eyes. They had carried the last defence of the old
counterscarp, and behold--a new one, which they had never dreamed of,
bristling before their eyes, with a flanking battery turned directly upon
them. The musketeers and pikemen, protected by their new works, now
thronged towards the assailants; giving them so hearty a welcome that
they reeled back, discomfited, after a brief but severe struggle, from
the spot of their anticipated t
