The Battle of Seedaseer was a battle of the Fourth Anglo-Mysore War on 6 March 1799 at Seedaseer (near present-day Siddapura, Karnataka), a hill and pass on the border of the Coorg and Mysore country seven miles from Piriyapatna and with a view almost as far as Seringapatam.

This was under Lieutenant-Colonel Montressor and was made up of what are now the 1st and 2nd Maratha Light Infantry battalions and the now-defunct 1st Bombay Pioneers.

Receiving news of a possible Mysorean march Stuart reinforced the advanced position with one more battalion of sepoys.

Stuart led the Left Brigade there as reinforcements by 2pm, forcing Tipu to withdraw.

The Governor-General wrote in his despatches to the British East India Company's directors "I am confident that your most honourable Court will be of the opinion that the conduct and success of the Army of Bombay on that day [at Seedaseer] has seldom been equalled and never surpassed.
