Sen points out that according to the "New Book of Tang", Lalitaditya's envoy came to the Tang court with a letter in March–April 933 CE. In this letter, Lalitaditya presents himself as a Tang vassal who had "submitted to the Heavenly Qaghan". Lalitaditya further explains that the Tibetans had distressed him and another king of Central India by blocking the five great routes. But the two Indian kings had managed to defeat the Tibetans. Finally, Lalitaditya requests the Tang army to arrive at Palur (present-day Gilgit-Baltistan), offering to set up a camp for them beside the Mahapadma lake (modern Wular Lake). He promises to supply provisions for the Tang army, even if it numbered as large as 200,000.
