No one has yet attempted to give any explanation of the monument beyond repeating the usual Druidical formulæ. To me it appears almost incontestable that it is a memorial of the battle fought here between the Saxons and the Danes in the year 871. From Asser we learn that the Pagans, advancing from Reading, occupied the higher ground. It is sometimes supposed that Uffington Castle was thrown up by them on the occasion, which is by no means impossible. Advancing eastward, they then attacked the Christians under Alfred, who occupied the lower ground. This, and the ill-timed fit of devotion on his brother's part, nearly lost the Christians the day; but Alfred's skill and intrepidity prevailed, and the victory was complete.[146] This being so, nothing appears more probable than that the victorious army, either by themselves or with the assistance of the peasantry, should have collected together the Sarsens in the neighbourhood, and have arranged them as Alfred and his army stood, when he first received the shock of the Pagans. It seems also probable that he would have engraved the emblem of the white horse on the side of the hill where the Pagans had encamped the night before the battle, and where probably the fight ended on the following day.
The question whether Weyland Smith's Cave belongs to the same group, or to an earlier date, is not so easily settled. My impression is that it is older. It is a three-chambered dolmen almost identical in plan with Petrie's No. 27, Carrowmore, to be described in the next chapter, but with this difference, that whereas the circle of stones in the Irish example contained thirty-six or thirty-seven stones, and was 60 feet in diameter, this one contained probably only twenty-eight, and was only 50 feet in diameter. This and the fact of the one consisting of Sarsens--the other of granite blocks--account so completely for all the difference between them, that I cannot believe that so great a lapse of time as eight centuries could have taken place between the erection of the two. I fancy it must have been erected for the entombment of a local hero in the early centuries of the Christian era; but of this we will be better able to judge when we are further advanced in our survey of similar monuments.
