Boulogne and Its Environs, France
Cartographer: [Rogers, John ]
This plan shows fortifications in Boulogne and the surrounding area. The town of Boulogne was built on two levels; the Haute Ville, occupying an area of rising ground which dominated the suburb known as the Basse Ville. The Haute Ville is shown here adjacent to the Basse Ville . It is a walled and fortified area with towers and the Castle in the top corner. It is thought to date from May – June 1546 and is almost certainly the work of military engineer John Rogers. It shows in detail the fortifications on both the French and English territories, which are on opposite sides of the river. Boulogne was important to Henry as it was neighbour to the English held Calais. The signing of a peace treaty by Charles V Holy Roman Emperor and King of Spain Francis I of France in 1538 meant that the French King could concentrate his forces on repelling his remaining enemy Henry VIII. Henry arrived in the newly taken Boulogne on September 18th and was immediately concerned with its fortification against the French. He found the defences had been weakened by the English attack and would not withstand a French attack without repair. On his return to England Henry left Lord Lisle in charge of a team which included John Rogers, a surveyor who had previously been master mason at Guines and was a military engineer of great experience. This plan shows both the English and the French territory on opposite sides of the river. The English territory is on the left hand side and shows the tower known as the ‘Old Man’ with a segmental bastioned wall defending it. A trench connects this to the citadel which is within the Basse Ville. Between these two point is the Young Man, a fortified structure which was built to reduce the vulnerability of the isolated but strategically valuable Old Man. Directly opposite the English fortifications is the five sided bastioned structure of the Fort De Chatillon which forms the focal point of the French defence system, consisting of defensive walls and enclosures. The plan is orientated to the east. Hills are shown in elevation and other terrain is described by text. The area is depicted at low tide. The dotted red line may indicate maximum English wishes during negations for Treaty of Camp. It is drawn on a scale of 1:6000.
