Nothing is more curious than a barricade preparing for an assault. Each man selects his place as though at the theatre. They jostle, and elbow and crowd each other. There are some who make stalls of paving-stones. Here is a corner of the wall which is in the way, it is removed; here is a redan which may afford protection, they take shelter behind it. Left-handed men are precious; they take the places that are inconvenient to the rest. Many arrange to fight in a sitting posture. They wish to be at ease to kill, and to die comfortably. In the sad war of June, 1848, an insurgent who was a formidable marksman, and who was firing from the top of a terrace upon a roof, had a reclining-chair brought there for his use; a charge of grapeshot found him out there.

As soon as the leader has given the order to clear the decks for action, all disorderly movements cease; there is no more pulling from one another; there are no more coteries; no more asides, there is no more holding aloof; everything in their spirits converges in, and changes into, a waiting for the assailants. A barricade before the arrival of danger is chaos; in danger, it is discipline itself. Peril produces order.
