Sikandar is the Persian name of Alexander the Great. Let us consider his behaviour in the case of the fortress of Massaga, Swat Valley. https://en.wikipedia.org/wiki/Indian_campaign_of_Alexander_the_Great
"A fierce contest ensued with the Aspasioi, in the course of which Alexander himself was wounded in the shoulder by a dart, but eventually the Aspasioi lost the fight; 40,000 of them were enslaved. The Assakenoi faced Alexander with an army of 30,000 cavalry, 38,000 infantry, and 30 elephants.[6] They had fought bravely and offered stubborn resistance to the invader in many of their strongholds such as the cities of Ora, Bazira, and Massaga. The fort of Massaga could only be reduced after several days of bloody fighting in which Alexander himself was wounded seriously in the ankle. When the Chieftain of Massaga fell in the battle, the supreme command of the army went to his old mother, Cleophis, who also stood determined to defend her motherland to the last extremity. The example of Cleophis assuming the supreme command of the military also brought the entire population of women of the locality into the fighting.[7][8] Alexander was only able to reduce Massaga by resorting to political strategem and actions of betrayal. According to Curtius: "Not only did Alexander slaughter the entire population of Massaga, but also did he reduce its buildings to rubbles".[9] A similar slaughter then followed at Ora, another stronghold of the Assakenoi."

"Alexander's retaliation against the defeated Assaceni was severe. He had Massaga burned. Victor Hansen writes: "After promising the surrounded Assaceni their lives upon capitulation, he executed all their soldiers who had surrendered. Their strongholds at Ora and Aornus, were also likewise stormed. Garrisons were probably all slaughtered."[9]
"Additionally, Alexander pursued the Kamboj mercenaries, surrounded them on a hill, and killed them all. Diodorus describes the event in detail: "...The women, taking up the arms of the fallen, fought side by side with their men. Accordingly, some who had supplied themselves with arms did their best to cover their husbands with their shields, while others, who were without arms, did much to impede the enemy by flinging themselves upon them and catching hold of their shields." [10][11][12]
Cleophis came to terms with the invaders and abandoned Massaga with her followers. Diodorus Siculus says: "Cleophis sent precious gifts to Alexander with a message that she expressed her appreciation of Alexander's greatness and assured him that she would comply with the terms of the treaty."[7] According to Curtius and Arrian, Cleophis was captured along with her young granddaughter.[8]
