Bretteville-sur-Laize was created as a permanent resting place for Canadian soldiers who had been temporarily buried in smaller plots close to where they fell. At the time of the cemetery's creation, France granted Canada a perpetual concession to the land occupied by the cemetery. The graves contain 2793 soldiers from the 2nd Canadian Corps, 91 of them unknown, and 79 RCAF airmen killed in the Battle of Normandy.
A large number of dead in the cemetery were killed late July 1944 around Saint-André-sur-Orne and in the battle for the Falaise Pocket in August 1944. Canadians killed earlier (June and early July) in the Battle of Normandy are buried near Juno Beach in the Bény-sur-Mer Canadian War Cemetery.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
