Fresh off the Negrais affair, the Anglo-Burmese relations remained decidedly frosty. While Naungdawgyi was laying siege to Ava, in September 1760, he received the English East India Company envoy Captain Walter Alves whose mission was to demand reparations for the Burmese sack of the English colony at Negrais in October 1759. The king refused to consider the demand but agreed to release English prisoners. He asked to resume trade as he was in urgent need of munitions. The English, still amid the Seven Years' War, did not deem the Burma trade profitable enough to resume trade.
