Next morning, having ascertained that Davidowich had not been engaged with Vaubois, Napoleon once more advanced upon Arcola. The place was once more defended bravely, and once more it was carried. But this second battle of Arcola proved no more decisive than the first; for Alvinzi still contrived to maintain his main force unbroken in the difficult country behind; and Buonaparte again retreated to Ronco. The third day was decisive. On this occasion also he carried Arcola; and, by two stratagems, was enabled to make his victory effectual. An ambuscade, planted among some willows, suddenly opened fire on a column of Croats, threw them into confusion, and, rushing from the concealment, crushed them down into the opposite bog, where most of them died. Napoleon was anxious to follow up this success by charging the Austrian main body on the firm ground behind the marshes. But it was no easy matter to reach them there. He had, in various quarters, portable bridges ready for crossing the ditches and canals; but the enemy stood in good order, and three days' hard fighting had nearly exhausted his own men. In one of his conversations at St. Helena, he thus told the sequel. "At Arcola I gained the battle with twenty-five horsemen. I perceived the critical moment of lassitude in either army--when the oldest and bravest would have been glad to be in their tents. All my men had been engaged. Three times I had been obliged to re-establish the battle. There remained to me but some twenty-five _Guides_. I sent them round on the flank of the enemy with three trumpets, bidding them blow loud and charge furiously. _Here is the French cavalry_, was the cry; and they took to flight."... The Austrians doubted not that Murat and all the horse had forced a way through the bogs; and at that moment Buonaparte commanding a general assault in front, the confusion became hopeless. Alvinzi retreated finally, though in decent order, upon Montebello. It was at Arcola that Muiron, who ever since the storming of Little Gibraltar had lived on terms of brotherlike intimacy with Napoleon, seeing a bomb about to explode threw himself between it and his general, and thus saved his life at the cost of his own. Napoleon, to the end of his life, remembered and regretted this heroic friend.
