Subsequent inquiries have, however, proved that the treachery towards the British was not on the part of Mehrab Khan, but on that of his vizier, Mahommed Hussein, and certain chiefs with whom he was in league, and at whose instigation the British convoys were plundered in their passage through Kach Gandava and in the Bolan Pass.
Besides these larger ramifications, there are the Gulfs of Cambay and Kach on the Indian coast.
This central desert is the Kir, Kej, Katz or Kash Kaian of Arabic medieval geography and a part of the ancient Kaiani kingdom; the prefix Kej or Kach always denoting lowlevel flats or valleys, in contradistinction to mountains or hills.
The kach is a sort of knickerbockers reaching to just below the knee, which they encircle tightly.
It would appear, however, that the sceptre was quietly transmitted to Abdulla Khan, the fourth in descent from Kambar, who, being an intrepid and ambitious soldier, turned his thoughts towards the conquest of Kach Gandava, then held by different petty chiefs under the authority of the nawabs of Sind.
