Mian Sadik Ali Khan Kalhoro was a king of the Kalhora Dynasty that ruled Sindh.
History
"The conquerors had hardly taken rest when a camelman brought to their camp a letter from Mír Fateh Alí’s brother Mír Ghulám Alí, informing them that Mián Abdunnabí had arrived as far as Ládkánah with a Boróhí force, that had been given to him by Muhammad Nasír, the Khán of Kalát, under the command of his son-in-law Zarak, on the understanding that the Mìan, when reinstated, would give him, in return, 3 laks of rupees and some part of his country; and that the army had been joined by Mehráb and Dhingánah Jatôís and by the Jhinjans, Khósahs, Nuhmardís and other tribes.
When Mír Abdulláh got this news, he did not ungirdle himself. He also required his comrades not to do so either. Without losing time, he started from there in the direction of the enemy whom he met at the bridge of Chálak. There he halted opposite the enemy’s camp, Mían Abdunnabí, believing that the Balóches had arrived there after hard travelling and that they must be exhausted with fatigue, advised his friends to attack them immediately and thus to gain an advantage over them.
Hastily therefore they drew up their army in three divisions, the centre being led by Mían Abdunnabí himself with the forces of the Jatóís and the Khósahs, the right wing consisting of the Kalátís or Bróhís under Zarak and the left of Nuhmardís. Seeing the advance of the enemy in the above order, Mír Abdulláh likewise divided his army in three divisions. He made Mían Sádik Alí Khán who had been brought on an elephant to the battle-field, with Mírzó Fakír and his son Bághah, go against Abdunnabí Khán. Mír Fateh Khán with the force of Nizámánís was appointed to fight with the Nuhmardís; while he himself with his cousin Mír Fateh Alí Khán on his right and Mír Suhráb Khán on his left, determined to meet the Bróhís.
The battle commenced with guns. After a brisk contest Mír Fateh Khán’s forces were pushed back. The Mír had received a bullet-wound in the last battle with the Rájpúts and that had more or less disabled him from fighting actively. At the same time Abdunnabí gained the upper hand over the column under Mían Sádik Alí and drove it back. Seeing this state of things Mír Abdulláh re-doubled his courage and called on his cousins to do the same. They left their horses and sword-in-hand made a vigorous attack on the centre of the enemy causing great confusion and killing Zarak Bróhí, Mehrab Jatóí and a number of other veteran soldiers. The result was that the enemy fled in confusion leaving much booty for the Balóches. Once more victorious, the Mían and the Mír returned to Khudábád."
