In Garibaldi's short absence at Palermo, the Southern Army (as he now called his forces) was left under the command of the Hungarian General Türr, as brave an officer as ever lived, and a fast friend to Italy, but his merits do not undo the fact that as soon as the Dictator's back was turned, everything got into a muddle. Pontoon bridges had been thrown across the river at four points; availing himself of one of these, Türr crossed the Volturno with a view to taking up a position on the right bank at a place called Caiazzo, a step which, if attempted at all, ought to have been supported by a very strong force. On the 19th of September, Caiazzo was actually taken, but on the 21st the Royalists came out of Capua with 3000 men and defeated with great loss the thousand or fewer Garibaldians charged with its defence, only a small number of whom were able to recross the bridges and join their companions. The saddest part of this adventure was the slaughter of nearly the whole of the boys' company--lads under fifteen, who had run away from home or school to fight with Garibaldi. Fight they did for five mortal hours, with the heroism of veterans or of children. Only about twenty were left. When Garibaldi returned from Sicily, this was the first news he heard, and it was not cheering. The Royalists, who thought they had won another Waterloo, were in the wildest spirits, and the march on Naples was talked of in their camp as being as good as accomplished. Garibaldi's lines were spread in the shape of a semi-circle, of which the two ends started from Santa Maria on the left, and Maddaloni on the right, with Castel Morone at the apex. The country is hilly, and this fact, together with the great distance covered, divided the 20,000 men into a number of practically distinct bodies, each of which, in the decisive battle, had to fight its own fight. Here and there improvised fortifications were thrown up. Garibaldi was aware that his line of battle was perilously extended, but the necessity of blocking all the roads and by-ways which led to Naples, dictated tactics which he was the last to defend.
