According to Goetz, Lalitaditya conquered present-day Bihar, Bengal and Odisha by 735-736 CE. Based on Kalhana's account, Goetz theorized that Lalitaditya marched to Gauda after defeating Yashovarman. There, he defeated the Later Gupta ruler Jivitagupta, and then advanced up to the Bay of Bengal through present-day Odisha. Goetz further theorized that Yashovarman supported Lalitaditya in these campaigns as a vassal. In the poem "Gaudavaho", Yashovarman's courtier Vakpati credits him with victories in eastern and southern India. The "Rajatarangini" makes similar claims for Lalitaditya. According to Goetz, the invasion routes described in both these texts are "practically identical". He, therefore, concludes that Yashovarman participated in Lalitaditya's wars as a vassal. Goetz argues that "Gaudavaho" fails to mention this, because Yashovarman's court poet wanted to whitewash his master's vassal status. "Gaudavaho" mentions that Yashovarman visited the Mandara mountain. According to Goetz, this is the poet's way of hiding Yashovarman's visit to Lalitaditya's court, which was located in the mountainous region.
