London Protocol (1944)

The basis of the ideas were the borders of Germany from 31 December 1937 (de) and Greater Berlin from 27 April 1920.

The north-western and south-western zones in Germany and Greater Berlin had not yet been assigned as British or American sub-areas.

Southwestern Zone: All the remaining territory of Western Germany situated to the south of the line defined in the description of the North-Western zone will be occupied by the armed forces of ------.This would have meant that the present-day states of Bavaria and Baden-Württemberg as well as the Palatinate, which previously belonged to Bavaria, and the southern part of the People's State of Hesse would have come to the southwestern (i.e. later American) zone, the Rhine province belonging to Prussia and the province of Hesse-Nassau and the northern part of the People's State of Hesse (Upper Hesse province) to the north-western, i.e. later British.

The city of Mainz, situated on both sides of the river, and its half on the right bank of the Rhine, was particularly affected by this the south-west zone, as the districts on the left bank of the Rhine including the city center were assigned to the north-west zone.

In order to enable the British and Soviet occupying forces to use the two airfields, immediately after the Potsdam Conference, an area swap was carried out on the western city limits of Berlin for the locations or parts of Weststaaken, Weinmeisterhöhe, the Seeburger Zipfel and the eastern part of Groß Glienicke.
