While in the camp, he persuaded Moortuza Nizam Shah to attack Ibrahim Kootb Shah's forces as well as those of Ally Bereed Shah, and by thus making a bold stroke at first, follow it up, and reduce the countries of Tulingana and Bidur. Moortuza Nizam Shah, young, thoughtless, and impetuous, eagerly adopted the proposition, and attacked his allies, who defended themselves with bravery, and contrived to retreat to Bidur, whence Ibrahim Kootb Shah proceeded to Golconda. On the return of Ibrahim Kootb Shah to his capital, he resolved to be revenged on Moortuza Nizam Shah for his late treachery; and as the latter always obtained assistance from the Berar court, he determined to anticipate that step by sending an envoy to Toofal Khan, the Regent of Berar, inviting him to an alliance against Moortuza Nizam Shah, to whom he could owe no friendship, since the invasion of his country, and the siege of Gavul. Toofal Khan, glad of an opportunity of revenging himself on Moortuza Nizam Shah, readily acceded to the proposed alliance, and despatched his son, Shumsheer-ool-Moolk, with three thousand cavalry to join Ibrahim Kootb Shah; who having collected his own army, proceeded, under the pretence of hunting, towards Bidur, when he was joined, between that city and the town of Kowlas, by the Berar auxiliaries, as well as by Ally Bereed Shah. Thence they deputed ambassadors to Ally Adil Shah, inviting him, also, to join the confederacy.
