The following information is taken from the Wikipedia:

[Khālid ibn al-Walīd ibn al-Mughīrah al-Makhzūmī (Arabic: خالد بن الوليد بن المغيرة المخزومي‎‎; 585–642), commonly known as simply Khalid ibn al-Walīd, and also known by his kunya as, Abu Sulaiman was a companion of Muhammad and an army commander under Abu Bakr and Umar ibn Khattab.^[1] It was under his military leadership that Arabia, for the first time, was united under a single political entity, the Caliphate. He then helped expand the Rashidun Caliphate during the early Muslim conquests, defeating armies of the Sasanian Persian Empire and Byzantine Roman Empire. Having remained undefeated, he is widely considered to be one of the greatest warriors and military generals in history.^[2][3][4]

Khalid ibn al-Walid (Khalid son of al-Walid) was from the Meccan tribe of Quraysh, from a clan that initially opposed Muhammad. He played a vital role in the Meccan victory at the Battle of Uhud against the Muslims. He converted to Islam, and joined Muhammad after the Treaty of Hudaybiyyah and participated in various expeditions for him, such as the Battle of Mu’tah, which was the first battle between the Romans and the Muslims. Khalid ibn Al-Walid reported that the fighting was so intense, that while fighting, he broke nine swords in the battle. This earned him the title ‘Saif-ullah’ meaning “The Sword of Allah”. Khalid took over after Zayd ibn Haritha, then Jafar ibn Abi Talib, then Abdullah ibn Rawahah were killed. After Muhammad’s death, he played a key role in commanding Medinan forces for Abu Bakr in the Ridda wars, conquering central Arabia and subduing Arab tribes. He captured the Sassanid Arab client Kingdom of Al-Hirah, and defeated the Sassanid Persian forces during his conquest of Iraq (Mesopotamia). He was later transferred to the western front to capture Roman Syria and the Byzantine Arab client state of the Ghassanids.

Although Umar later relieved him of high command, he nevertheless remained the effective leader of the forces arrayed against the Byzantines during the early stages of the Byzantine–Arab Wars.^[1] Under his command, Damascus was captured in 634 and the key Arab victory against the Byzantine forces was achieved at the Battle of Yarmouk (636),^[1] which led to the conquest of the Bilad al-Sham (Levant). In 638, he was dismissed from military services by Umar because of people’s overconfidence on him, causing shirk.

Khalid fought around 200 battles, both major battles and minor skirmishes as well as single duels, during his military career.]
