Following the operations of the German armies from the battle of Gravelotte to the siege of Paris, I may, in conclusion, say that I saw no new military principles developed, whether of strategy or grand tactics, the movements of the different armies and corps being dictated and governed by the same general laws that have so long obtained, simplicity of combination and manoeuvre, and the concentration of a numerically superior force at the vital point.
After my brief trip to Versailles, I remained in Paris till the latter part of March. In company with Mr. Washburn, I visited the fortifications for the defense of the city, and found them to be exceptionally heavy; so strong, indeed, that it would have been very hard to carry the place by a general assault. The Germans, knowing the character of the works, had refrained from the sacrifice of life that such an attempt must entail, though they well knew that many of the forts were manned by unseasoned soldiers. With only a combat here and there, to tighten their lines or repulse a sortie, they wisely preferred to wait till starvation should do the work with little loss and absolute certainty.
The Germans were withdrawn from Paris on the 3d of March, and no sooner were they gone than factional quarrels, which had been going on at intervals ever since the flight of the Empress and the fall of her regency on the 4th of September, were renewed with revolutionary methods that eventually brought about the Commune. Having witnessed one or two of these outbreaks, and concluding that while such turbulence reigned in the city it would be of little profit for me to tarry there, I decided to devote the rest of the time I could be away from home to travel in England, Ireland, and Scotland. My journeys through those countries were full of pleasure and instruction, but as nothing I saw or did was markedly different from what has been so often described by others, I will save the reader this part of my experience. I returned to America in the fall, having been absent a little more than a year, and although I saw much abroad of absorbing interest, both professional and general, yet I came back to my native land with even a greater love for her, and with increased admiration for her institutions.
