The canal offers watercraft a shorter journey between the North Atlantic and northern Indian Oceans via the Mediterranean and Red seas by avoiding the South Atlantic and southern Indian oceans, in turn reducing the journey by approximately 7000 km .  It extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez.  Its length is 193.30 km , including its northern and southern access channels.

An Ottoman force led by the German General Friedrich Freiherr Kress von Kressenstein made a surprise attack on three and a half squadrons of the British 5th Mounted Brigade, which was widely scattered to the east of Romani.  The mounted brigade had been ordered to the area to protect the new railway and water pipeline being built from Kantara on the Suez Canal, as this infrastructure extended out past the Canal's zone of defences into the Sinai Peninsula towards Romani.  Kress Von Kressenstein's attack was completely successful, decimating the equivalent of little more than a regiment.  On the same day, an associated Ottoman attack on Duidar, very close to the Suez Canal, failed when it met with strong British opposition.
