Israel responds to a build-up of Arab forces along its borders by launching a preemptive aerial attack against Egypt. Jordan subsequently entered the fray, but the Arab coalition was no match for Israel’s armed forces. In six days of fighting, Israel occupied the Gaza Strip and the Sinai Peninsula of Egypt, the Golan Heights of Syria and the West Bank and Arab sector of East Jerusalem, both previously under Jordanian rule. By the time the United Nations cease-fire took effect on June 11, Israel had more than doubled its size, including claiming the Old City of Jerusalem from Jordan.

During the Six-Day War, Israeli aircraft and torpedo boats attack the USS Liberty in international waters off Egypt’s Gaza Strip. The intelligence ship, well-marked as an American vessel and only lightly armed, was attacked first by Israeli aircraft that fired napalm and rockets at the ship. The Liberty attempted to radio for assistance, but the Israeli aircraft blocked the transmissions. Eventually, the ship was able to make contact with the U.S. carrier Saratoga, and 12 fighter jets and four tanker planes were dispatched to defend the Liberty. When word of their deployment reached Washington, however, Secretary of Defense Robert McNamara ordered them recalled to the carrier, and they never reached the Liberty. The reason for the recall remains unclear.

The Six-Day War between Israel and its Arab neighbors ends with a United Nations-brokered cease-fire. The outnumbered Israel Defense Forces achieved a swift victory in the brief war, rolling over the Arab coalition and more than doubling the amount of territory under Israel’s control. The greatest fruit of victory lay in seizing the Old City of Jerusalem from Jordan; thousands of Jews wept while bent in prayer at the Second Temple’s Western Wall.

The following day, the headline in the London Daily Mirror read “EPSTEIN (The Beatle-Making Prince of Pop) DIES AT 32.” Brian Epstein was, by all accounts, the man who truly got the Beatles off the ground, and in John Lennon’s estimation, it was difficult to see how they’d manage to go on without the man who had managed every aspect of the Beatles’ business affairs up until his unexpected death. “I knew that we were in trouble then,” John later recalled. “I didn’t really have any misconceptions about our ability to do anything other than play music. I was scared. I thought, ‘We’ve ******* had it.'”

On August 30, 1967, Thurgood Marshall becomes the first African American to be confirmed as a Supreme Court justice.

The film The Graduate opens at two theaters in New York: the Coronet on Third Avenue and the Lincoln Art Theater on Broadway.

Anne Bancroft and Dustin Hoffman starred.
