In spite of the vigorous efforts made by the commander-in-chief Trochu, both by continuous firing from the forts and by repeated sallies, to prevent Paris from being surrounded, and to force a way through the trenches, his enterprises were rendered fruitless by the watchfulness and strength of the Germans. The blockade was completely accomplished; Paris was surrounded and cut off from the outer world; even the underground telegraphs, through which communication was for a time secretly maintained with the provinces, were by degrees discovered and destroyed. But to the great astonishment of Europe, which looked on with keenly pitched excitement at the mighty struggle, the siege continued for months without any special progress being observable from without or any lessening of resistance from within. On account of the extension of the forts, the Germans were compelled to remain at such a distance that a bombardment of the town at first appeared impossible; a storming of the outer works would, moreover, be attended with such sacrifices, that the humane temper of the king revolted from such a proceeding. The guns of greater force and carrying power which were needed from Germany, could only be procured after long delay on account of the broken lines of railway. Probably also there was some hesitation on the German side to expose the beautiful city, regarded by so many as the "metropolis of civilization," to the risk of a bombardment, in which works of art, science, and a historical past would meet destruction. Nevertheless, the declamations of the French at the Vandalism of the northern barbarians met with assent and sympathy from most of the foreign powers.
