On October 4, 1973, only two days before the Yom Kippur War, over 93% of Egypt's officers did not know that Egypt was about to stage a surprise attack on Israel, according to newly declassified protocols from the Agranat Commission.
The new revelations came Sunday from the commission's now declassified questioning of former IDF head of the southern command Maj. Gen. (res.) Shmuel Gonen, which came out of a larger batch of protocols of six top IDF intelligence officials.
While numerous theories have arisen as to how the IDF could have been surprised as badly as it was initially, one has been that the surprise attack was kept under wraps even on the Egyptian side.
The fact that only 18 out of 281 Egyptian officers and captured and interrogated by the IDF knew that Egypt was planning an attack as late as October 4, and only another seven knew as of October 5, with the rest being about as surprised as Israel, does provide support for this theory.
