 As a result, the city of Bostra surrendered, and the Palmyrene army captured and sacked the city, and destroyed the temple of Zeus Hammon, the legion's revered shrine.In October of 270, a Palmyrene army of 70,000 invaded Egypt, led by Zabdas.The invasion of Egypt is sometimes explained by Zenobia's desire to secure an alternative trade route to the Euphrates, which was cut because of the war with Persia, although the Euphrates route was only partially disrupted, and Zenobia's personal ambition and political motivation to establish Palmyrene dominance over the east definitely played a part in her decision to invade Egypt.
