I touched my hat and, turning upon my heel, proceeded forthwith to scramble up the steep face of the cliff, helping myself up by driving my drawn cutlass deep into the stiff clay soil of which the cliff was composed.  Reaching the top without much difficulty, I found myself upon somewhat uneven ground, the surface of which sloped slightly down toward the land.  The soil was clothed with short, thick grass and closely overgrown with dense clumps of furze bushes, which I at once perceived would afford excellent cover for the approach of our men.  Somewhat to my discomfiture, however, I saw a flock of sheep grazing at no great distance inland, while about a mile away to the south-west was a small village, in the single street of which I could perceive people already moving about.  Clearly, we had no time to lose if we wished to take our friends the enemy by surprise; availing myself, therefore, to the utmost extent of the cover of the furze bushes, I set off in the direction of the battery, which I presently sighted about half a mile away.  Stooping low as I ran from bush to bush, and peering cautiously round each before venturing to start for the next, I soon found myself within about thirty yards of the battery, which I saw to be a crescent-shaped affair, facing eastward and thus in conjunction with the battery on the opposite point, completely commanding the entrance of the bay.  It was in reality a brick-work structure, consisting of four chambers with arched roofs supporting a gun platform protected by a parapet pierced with embrasures, the brick-work in its turn being protected by an earth-bank thrown up in front of it in the form of a glacis.  It mounted six 64-pounders; and the chambers beneath the gun platform I took to be the magazine, general store-room, and soldiers' quarters.  The gun platform was approached at either end by a good wide flight of steps; and beside each gun was a goodly pile of shot, while sponges, rammers, handspikes, and the rest of the paraphernalia for loading and training the guns reposed in brackets fixed to the inner face of the parapet.  Two sentries were stationed upon the gun platform, pacing to and fro, and evidently keeping a sharp lookout to seaward, and a number of artillerymen were performing their morning ablutions, brushing their clothes, etcetera, in the paved space before the chambers.  Strangely enough, the back of the battery was left perfectly open and unprotected by either wall or fence; there was therefore absolutely nothing to prevent its being rushed from the land side.  I counted the men in sight to the number of thirty-three, but concluded that there must be others somewhere inside the chambers; and then, having acquired all the information possible under the circumstances, made the best of my way back to where Mr Adair and the rest of our party impatiently awaited me.
