Universal amnesty was proclaimed for all offences and quarrels.  Every citizen or resident foreigner was free to remain in or to retire from the town or province, with full protection to his person and property, and it was expressly provided in the articles granted to Lanckema that his soldiers should depart with arms and baggage, leaving to Prince Maurice their colours only, while the prince furnished sufficient transportation for their women and their wounded.  The property of Verdugo, royal stadholder of the province, was to be respected, and to remain in the city, or to be taken thence under safe conduct, as might be preferred.

Ten thousand cannon-shot had been fired against the city.  The cost of powder and shot consumed was estimated at a hundred thousand florins.  Four hundred of the besiegers had been killed, and a much larger number wounded.  The army had been further weakened by sickness and numerous desertions.  Of the besieged, three hundred soldiers in all were killed, and a few citizens.

Thirty-six cannon were taken, besides mortars, and it was said that eight hundred tons of powder, and plenty of other ammunition and provisions were found in the place.

On the 23rd July Maurice and William Lewis entered the city.  Some of the soldiers were disappointed at the inexorable prohibition of pillage; but it was the purpose of Maurice, as of the States-General, to place the sister province at once in the unsullied possession of the liberty and the order for which the struggle with Spain had, been carried on so long.  If the limitation of public religious worship seemed harsh, it should be remembered that Romanism in a city occupied by Spanish troops had come to mean unmitigated hostility to the republic.  In the midst of civil war, the hour for that religious liberty which was the necessary issue of the great conflict had not yet struck.  It was surely something gained for humanity that no man should be questioned at all as to his creed in countries where it was so recently the time-honoured practice to question him on the rack, and to burn him if the answer was objectionable to the inquirer.

It was something that the holy Inquisition had been for ever suppressed in the land.  It must be admitted, likewise, that the terms of surrender and the spectacle of re-established law and order which succeeded the capture of Groningen furnished a wholesome contrast to the scenes of ineffable horror that had been displayed whenever a Dutch town had fallen into the hands of Philip.

And thus the commonwealth of the United Netherlands, through the practical military genius and perseverance of Maurice and Lewis William, and the substantial statesmanship of Barneveld and his colleagues, had at last rounded itself into definite shape; while in all directions toward which men turned their eyes, world-empire, imposing and gorgeous as it had seemed for an interval, was vanishing before its votaries like a mirage.  The republic, placed on the solid foundations of civil liberty, self-government, and reasonable law, was steadily consolidating itself.
