In 1891, the regiment was localized to the Province of Baluchistan and reconstituted with Balochis, Brahuis, Pathans and Punjabi Muslims.

It adopted uniforms of drab colour with red trousers and its designation was changed to 26th (Baluchistan) Regiment of Bombay Infantry.

The battalion was taken prisoner by the Japanese on Singapore Island after the surrender of British forces on 15 February 1942.

The battalion won distinction for resisting intense enemy pressure to join the Japanese-sponsored Indian National Army.

Prominent among them was Lieutenant Abrar Hussain, who was awarded the MBE for his heroic conduct whilst a Prisoner of War.
