After proceeding a short distance, Fane's brigade moved off from the road and marched along the valley, equidistant from the main body and from Ferguson, forming a connecting link between them; and on reaching the village of St. Mamed, three-quarters of a mile from the French position, Hill's brigade turned off to the right. From their elevated position the French opened fire with their artillery, and this was answered by the twelve guns in the valley and from Ferguson's six guns on the heights. Fane's brigade, extended to its left, was the first in action, and drove back the French skirmishers and connected Ferguson with the centre. They then turned to attack the right of the French position; while Ferguson, seeing no signs of Loison's force, descended from the high ground to the rear of Fane, while the Portuguese pressed forward at the foot of the hills on the other side of the valley and threatened the enemy's left flank. [Illustration: BATTLE OF ROLICA map.] Seeing that his position was absolutely untenable, Laborde did not wait the assault, but fell back, covered by his cavalry, to the far stronger position in his rear. A momentary pause ensued before the British continued their advance. The new position of the French was of great natural strength, and could be approached only by narrow paths winding up through deep ravines on its face. Ferguson and Fane received orders to keep to the left, and so turn the enemy's right. Trant similarly was to push forward and threaten his left flank, while Hill and Nightingale advanced against the front. The battle commenced by a storm of skirmishers from these brigades running forward. These soon reached the foot of the precipitous hill and plunged into the passes. Neither the fire of the enemy nor the difficulties of the ascent checked them. Spreading right and left from the paths they made their way up, and taking advantage of the shelter afforded by great boulders, broken masses of rock, and the stumps of trees, climbed up wherever they could find a foothold. The supporting columns experienced much greater difficulty; the paths were too narrow, and the ground too broken for them to retain their formation, and they made their way forward as best they could in necessary disorder. The din of battle was prodigious, for the rattle of musketry was echoed and re-echoed from the rocks. The progress of the skirmishers could only be noted by the light smoke rising through the foliage and by the shouts of the soldiers, which were echoed by the still louder ones of the French, gathered strongly on the hill above them. As the British made their way up, Laborde, who was still anxiously looking for the expected coming of Loison, withdrew a portion of his troops from the left and strengthened his right, in order to hold on as long as possible on the side from which aid was expected. The ardour of the British to get to close quarters favoured this movement.
