This could have prevented the disaster of September 22_, 1867_, and the combination would probably have carried the works. But the Allies knew nothing of mining ; the plan was allowed to lie upon the Generalissimo Mitre^s desk^ and the attack was made in the bull-headed style before described.

At this j^oint the enemy had been more than usually active : the parapet and covered way were often built over swamps for many yards^ and plank bridges (pontilhoes) had been carefully laid down.

At the Angulo we found a brother of our guide, with
