The Treaty of Deogao (1803) was signed between Lord Wellesley (not Cornwallis) and Raghujee Bhonsle II of Nagpur. The other treaties are correctly matched: Amritsar (1809) between Lord Minto and Ranjit Singh, Purandhar (1816) between Warren Hastings and Marathas (after Third Anglo-Maratha War), and Sugauli (1816) between Lord Hastings and Nepal ruler.
