How did Muhammad conquer Mecca?

Answer 1

People of Mecca surrendered to Prophet Muhammad (PBUH) and his followers without fighting. Although Muslims suffered from the oppression of the disbelievers of Mecca and although when the prophet and his followers immigrated from Mecca they left behind their money and properties. Prophet Muhammad(PBUH) forgave all of them, destroyed all the idols around Kaaba, and returned to Medina with his followers without causing any harm or damage to people of Mecca or to their properties.

Answer 2

Muhammad PBUH conquered with his Muslim companions the city of Makkah without fighting. He forgave the Makkan people in a historical act of grace despite the too much harm they caused to Muslims, even the reason for conquering Makkah was because of breaking the treaty of Al-Hudaebeah by the pagans of Makkah.

This event took place in the 17th of Ramadan, 8 Hijri.
