The October war files — released by the Egyptian Ministry of Defence earlier this month for the first time since 1973 — put the Egyptian army's ability to defend Egyptian territories under sharp focus.
The declassification of the files comes at a time of high tension with Israel, against the background of its current war on Gaza and plans by the Israeli army to invade Rafah — the furthest-south area where around 1.4 million Palestinians are displaced from the northern and central parts of the Palestinian territory.
The files give rare insights into the Egyptian army's plans for different battles in the war and the success of Egyptian troops in dealing with some operational pitfalls.
This includes what came to be known as Operation Gazelle, which was staged by Israel on 16 October 1973, exploiting a gap between the 2nd and 3rd Egyptian field armies in Ismailia — a city that overlooks the Suez Canal.

The files also shed light on support offered by Arab countries to Egypt during the war as the Egyptian army battled to regain Sinai, which was occupied by Israel in 1967.
The October war of 1973 caused seismic shifts in regional political conditions and major alterations in the regional order.
50 years on
The declassification of thousands of original files, dating back to the 1973 October war against Israel, was supposed to coincide with the 50th anniversary of the war in October last year.
The Egyptian Ministry of Defence formed a panel of war veterans in August last year to review the files before declassifying them.
The war veterans should have finalised their review of the files by October.

"The mission of reviewing the files was far from easy because we had to scrutinise every single document to make sure that we are not publicising any sensitive information about the army," Gen. Nasr Salem, an October war veteran and a member of the panel, told Al Majalla.
The Ministry of Defence published the documents on its website under the title '1973 October War Documents: War Secrets – Strategic and Military Planning'.
Almost 40% of the documents published were handwritten by army commanders during the war. They cover major turning points in the war, including the destruction by the Egyptian army of the Bar Lev Line — a chain of fortifications built by Israel along the eastern bank of the Suez Canal to prevent the Egyptians from crossing the canal and entering Sinai.
One of the documents dated 22 April 1973 is addressed to the naval operations chief. The letter refers to a previous request to offer the necessary cover for troops fighting on the eastern bank of the Gulf of Suez in what came to be known as Operation Granite 2.
Another document talks about the Chinese Farm battle — an offensive launched by army troops on 26 October 1973 in reaction to Operation Gazelle.
The documents include dozens of maps, hundreds of letters, and transcriptions of communications between different Egyptian army commanders and officers.
They cover a wide range of developments during the war in full detail, including also coordination between the Egyptian and Syrian armies ahead of and during the October War.
