After this loss the affairs of Boorhan Nizam Shah declined daily; and numbers of his troops, tired of a long and fatiguing campaign, deserted from his camp; and a conspiracy was formed against his life by several of the officers, who wished to place his son Ismael upon the throne in his stead. Discovering the plot, and growing suspicious of all around him, he began his retreat towards Ahmudnuggur; but was so harassed on his first march that he thought it imprudent to attempt moving further till he could make peace with Ibrahim Adil Shah, to whom he sent ambassadors to treat, and for which purpose he halted at Kurmulla. Ibrahim Adil Shah for nearly a whole month refused to listen to any accommodation, till he compelled Boorhan Nizam Shah to destroy the fort he had erected within his territory, on the bank of the Beema, which he reluctantly did, throwing down the first stone with his own hands; after which his troops demolished the whole fabric, which had cost much trouble and expense. He then marched expeditiously back to Ahmudnuggur, heartily repenting of his unprovoked invasion of the territories of Ibrahim Adil Shah. The King's affairs being now restored to order, he resolved to humble the rays of Malabar, who, since the recall of Buleel Khan, had neglected to pay their tribute. For this purpose he despatched Munjun Khan with a considerable army.
