Umar's armies were now fighting on two fronts and he knew that time was against him. Therefore his Asian army commander Khalid ibn al-Walid was ordered to advance deeper into Persia. However, when Khalid's armies reached the outskirts of the Persian capital, Parsa, he found out that the Empire was already fighting at her limit against the invading Mongolian horse archers. This suited Khalid very well and he quickened his army's pace.
As the Khalid's Camel Riders progressed, they encountered some scattered Mongolian troops, which were easily destroyed by the heavier Riders.
Meanwhile in Egypt Umar's Army had reached the borders of the ancient Egyptian capital of Niwt-Rist. Umar sent his Levant Riders ahead to strike first before the city was warned. Their surprise attack was succesful and a complete Khoisan mercenary archer unit was destroyed.
The main army arrived soon after and joined the battle. The Egyptians weren't expecting more Arab reinforcements and their morale crumled. The Arabs gained the upper hand and poured against the city on every front. The Egyptians were doomed and the city fell. Umar renamed the city Al-Uqsur.
After the city was secured Umar turned his main army around and marched against the last important Egyptian city of Per Wadjet. The Egyptian armies were in disarray and leaderless and the resistance was feeble. The city was taken without signicant losses. Thus the Egyptian cilivization was destroyed and Umar know controlled the fertile lands of Egypt.
In Persia Khalid's armies had reached Parsa and Khalid himself lead the 1st Riders of Makkah to the first attack against the feared Persian War Elephants. The battle was fierce and many of these veterans were pierced by elephants tusks or trampled to death. However, Khalid's superior tactics and veteran Riders managed to kill these beasts one by one.
The attack continued and Khalid's catapults softened the defences before he ordered a full attack against the city. The fierce Beduain Riders broke through almost instantly and the defences fell as the walls were breached. However, Khalid and 1st Riders of Makkah were the first to reach the city centre. Parsa had fallen and Persian Empire was crumling. It was only a matter of time before Khalid's Armies would tear down this ancient civilization.
After taking control of Persia's heartlands Khalid met with the Indian emissaries and traded knowledge about meditation with them.
These past decades are known for the ruthless and merciless Arabian expansions. During this Era three, if Babylon is included, ancient Empires basicly ceased to exist, although Persia fought on for some years, and the Arabian influence spread even wider.
