The Suez base and the 1956 invasion of Egypt
After Egypt nationalised the Suez Canal, Britain and France invaded in coordination with Israel to seize the canal zone that had long hosted a huge British military base. The operation captured Port Said but collapsed under United States and Soviet pressure, forcing a humiliating withdrawal. Suez marked the limits of Britain's ability to hold its old imperial bases by force.
The failed invasion of Nasser's Egypt began on October 29, 1956.
