The day of the attack was chosen with care. October 6 was the date of Yom Kippur, the Day of Atonement. It is one of the holiest days in the Jewish calendar, and is a strict Sabbath day, which means no work may be performed on that day. As a result, many Israeli soldiers were not at their posts, and Israel was literally caught off guard. Iraq and Jordan stepped in to support the other Arab forces, and the United States airlifted weapons to Israel. Gradually the Israel Defense Forces reclaimed the territory that had been taken back by the Arabs. The United Nations issued a cease-fire resolution on October 22, and open hostilities finally ended on October 26. Israel technically won the war, but sustained heavy casualties and loss of military equipment. The reputation of Anwar el-Sadat, Egypt’s president, grew throughout the Middle East due to his forceful and decisive attacks at the beginning of the war, and he claimed it as an Egyptian victory.
