After his defeat, Shuja retreated towards Bengal. He was pursued by the imperial army under Mir Jumla. Shuja put up a good fight against them. However, he was finally defeated in the last battle in April 1660. After each defeat, he had to face desertions in his own army, but he did not lose heart. Rather, he reorganised the army with renewed vigor. But when he was surrounded at Tanda and found that reorganisation of the army was no longer possible, he decided to leave Bengal for good and take shelter in Arakan.
