Firishta's History (Gulshan-i Ibrāhīmī) 119.4.2

119.4.2

With the aid of the Berar troops, Moortuza Nizam Shah marched to Kowlas, by which time the troops of Ibrahim Kootb Shah had also moved, and a junction was effected between the towns of Kand'har and Kowlas, where a treaty was formed. It was resolved that the united forces of Ahmudnuggur, Berar, and Golconda, should march direct to the attack of Beejapoor. Ally Adil Shah, deserting his capital in his turn, retreated to the Concan, leaving a considerable army for the defence of the city, while the allies laid siege to Beejapoor, and laid waste the surrounding country. Ibrahim Kootb Shah, perceiving that Ally Adil Shah was driven from one spot to another, and unwilling that he should be reduced to cede any large tract of country to Moortuza Nizam Shah, contrived to persuade the other allies to raise the siege, and to return to their own capitals. After this event, Ally Adil Shah made secret overtures of alliance to Moortuza Nizam Shah, and proposed they should meet at the fort of Owsa. Here they entered into a compact, by which it was agreed that Moortuza Nizam Shah should reduce the kingdom of Berar, and Ally Adil Shah those of Bidur and Tulingana.
