Suddenly loud shouts were heard in advance of the right. A roar of musketry immediately broke out. Covered by the inequalities of the ground, the French had crept up unobserved by the sentries until close at hand, and the moment the alarm was given, sprang forward in great force, and the advanced pickets fell back on the main position at once. A heavy column of French advanced against a ruined wall, behind which the 58th were lying. The wall was of considerable length, and in many places had fallen and left wide openings. Here the 58th were posted. Their colonel made his men hold their fire until the enemy were close to them, when volley after volley was poured into them, so well aimed and deadly that the enemy retired quickly into a hollow in their rear, then wheeled round to the right, and while one column marched straight at the newly-formed battery, another endeavoured to force its way round its left and take it in rear.
