Sikandar Khan was appointed as a commander of an army and took part in many expeditions across
Bengal. He defeated Raja Matuk of the
Sundarbans in
South Bengal. He accompanied Firuz in the conquests of
Sonargaon and
Satgaon, before reaching the
Sylhet region.
Shaykh Burhanuddin, a Muslim living in
Tultikar, Gour, notified
Shamsuddin Firuz Shah of the injustice he was facing and Firuz ordered Sikandar to lead the expedition to
Gour Kingdom. Sikandar's army, however, were inexperienced in the foreign hilly terrain and had no option but to retreat back to Bengal to avoid casualties. When
Shah Jalal arrived in Bengal, Sikandar met him and greeted him with respect. He asked the cleric to join him in the expedition and that it is not the Raja's wealth and property which he wants but rather to propagate
Islam in the Sylhet region. With the assistance of Shah Jalal and
Syed Nasiruddin, the
Conquest of Gour was successful. The King of the Gour Kingdom, Raja
Gour Govinda escaped to
Harong Hurong cave and was never heard of again. Following the conquest, Sikandar was made the
wazir and ruled over Sylhet. He reportedly ruled from modern-day
Badarpur in
Karimganj towards the east of the
Sylhet region. Ghazi's drawing room can be seen in the village of Gorkapon sitting on the banks of the
Barak River. ==Death==
