I profess to send you mere sketches of the revolution—not its history, which the newspapers have already in great measure supplied—and therefore I do not consider myself bound to trace all its events, but limit myself chiefly to what I saw. An artist who should have perambulated Madrid during the 19th and 20th July would have found abundant and striking subjects for his pencil. Feverish activity was the characteristic of the first day, armed and vigilant repose of the second. Repose from fighting, but not from toil, for, although there was a cessation of hostilities—the Principal having surrendered (not, however, until the afternoon of the 20th, when its garrison was literally starved out), the whole town, with the exception of a few barracks and buildings at its extremities, being in the possession of the insurgents, and the Queen having sent for Espartero, which was all that Madrid asked—the insurgents were still mistrustful, and in no way relaxed their watchfulness. The medley of arms amongst them—particularly on the 19th, for on the 20th they were better supplied with muskets—was curious to observe. Many had scabbardless swords, which they used as walking-sticks, thereby greatly improving the point; others had pistols, some of tremendous length and most antiquated construction. There were not a few _trabucos_ to be seen. These are tremendous blunderbusses, wide at the mouth, which scatter a handful of _postas_ (large slugs), or carry a ball full four times the size of a musket-ball. Here is a man with a curved scimitar, which must have been handed down to him from some Moorish ancestor, bound to his waist by a bit of old sash; yonder, on a door-step, out of the exact range of fire, but the bullets striking from time to time the balcony above her head, sits a woman playing with a dagger, which she looks quite capable of using. I write only what I myself observed. On the morning of the 20th I walked round many of the barricades when their defenders were breakfasting. One group had got a guitar for a table. It rested on the knees of a circle, and supported their bread and sausage. There was great sobriety; during the whole of the revolution I saw no case of drunkenness.
