John Shipp, Memoirs of the Extraordinary Military Career of John Shipp
“ On the following day I visited the strong hill fort of Callenger. It is situated on an immense hill, on the ascent of which the greater part of the town stands. At the extremity of this ascent, the rocks are almost perpendicular. In some places they are fifty and sixty feet high. On these are built prodigious bastions and stone walls, with embrasures and loop-holes, so that any approach by assault or escalade was impossible. On its summit is a beautiful tank of clear water, nourished by a crystal spring. There are also fields, gardens, and woods, and two or three temples or mosques. ”
