army in Gujarat, and had also urged him to kill Simhana to avenge his father's death. This letter convinced Simhana that Shankha and Devapala were conspiring against him. It appears that Simhana withdrew from the planned invasion, and the Chaulukya-Yadava conflict came to end in c. 1232 with a peace treaty. Historian A. S. Altekar speculates that Simhana must have received considerable wealth for agreeing to this peace treaty, in addition to the confirmation of his protectorate over the Lata region. The 13th century text Lekhapaddhati, which provides specimens for different types of letters, includes a text of the peace treaty between Lavanaprasada and Simhana. However, this appears to be a specimen rather than a true historical document. In the 1240s, Lavanaprasada's grandson Visaladeva usurped the power in Gujarat, and became a monarch. During his reign, Simhana's forces invaded Gujarat unsuccessfully. Simhana's general Rama (a son of Kholeshvara) was killed in this campaign. The Yadavas' conflict with Gujarat ultimately weakened both the kingdoms, and paved way for the Muslim conquest of these kingdoms half a century after Simhana's death. Southern feudatories The Ratta chiefs ruled a small principality in the present-day Belgaum district, and kept shifting their allegiance between the dominant imperial powers of the region. Sometime during 1228-1238, Simhana's general Bichana appears to have conquered the Ratta principality. The last Ratta ruler was Lakshmideva II, and he is last known to have ruled in 1228. By 1238, Bichana ruled the former Ratta territory as a feudatory of Simhana. Bichana also subdued other chiefs, such as the Guttas of Dharwad, the Kadambas of Hangal, and the Kadambas of Goa. These chiefs kept shifting their allegiance between the Hoysalas and the Yadavas, and tried to become independent whenever presented with an opportunity. Bichana inflicted severe punishments on these chiefs for their insubordination. In 1237, the Gutta chief rebelled against Simhana, and even raided the Yadava territory. Simhana sent a 30,000-strong cavalry against him: this army captured the Gutti fort. Other victories The Yadava records contain exaggerated accounts of Simhana's other victories. For example, one inscription states that Simhana was: The court poet Hemadri mentions that Simhana captured the elephant force of King Jajalla, and ended the sovereignty of King Kakkula. The name Jajalla sounds like that of the Ratnapura Kalachuri rulers of present-day Chhattisgarh, but no king named Jajalla was a contemporary of Simhana. The last known ruler bearing this name
