Study, 30. June
Germann refers to his first report of the 22.6.40. The idea of the Réduit was formulated as follows by
"Aber es soll, nachdem bereits durch Grenz-
und Vortruppen dem Gegner erhebliche Verluste beigebracht und seine Operationen
durch Zerstörungen, Tanksperren und andere geeignete Mittel verzögert worden
sind, noch das Gros der Armee nachhaltigen Widerstand leisten können. Die
Reduitstellung hat nach meiner Ansicht den Zweck, durch diese Widerstandskraft
die Existenzberechtigung eines unabhängigen Schweizervolkes zu erweisen und den
Landesbehörden zu erlauben, in ihrem Schutz auf freiem Schweizerboden frei ihre
Entschlüsse zu fassen."
"After the border troops and and the advanced
troops have already incurred significant losses to the enemy and the enemy
operations have been delayed through the destruction work, the tank obstacles
and other means, the bulk of our army should still be able to resist for a long
period of time. The reduit position through its strength, in my opinion, has the
purpose to prove the right of existence of the Swiss people and to allow its
government to take its decision under the protection of the reduit on free Swiss
Germann proposed to move the
core of the required troops to the central redoubt in advance. The troops in the
advanced position (army position) should stay and fight.
The Réduit in his planning was considerably
smaller, than the actual one chosen in the Operationsbefehl No 12. Germann
assumed, that the number of divisions would have to be limited in order to allow
a long term survival under siege.
Like Gonard he didn't want to
defend the canton of Glarus, the town of Lucerne and the Napf area. Germann
proposed to create three main groups: Gotthard, Unterwalden/Brünig and Bernese

Study, 1. July 1940
(Col Gonard, Chief of
the Operations Section)
The chief of the operations section submitted its
study on 1. July 1940. It analysed in depth the size and borders of the Réduit
and proposed three different options. The different options are discussed on 17
pages, the defense of the advanced position and the task of the border troops on
Goal of the Réduit National
Gonard states that the aim of
the "réduit national" was to keep possession of as many alpine passes as
The minimum solution would
have been to control at least the passage of the Gotthard and of the Lötschberg
(the two main railway passages through the alps).
here for a large version with explanations - opens a new window)
The maximum solution would
have been to control the Rhine and Rhone valley at Sargans and St. Maurice
respectively and to keep control of the minor (no railway passage) passes in the
Grisons. With this solution the Swiss army would have to control:
240 kms of frontline (Sargans
- Zug - Sursee - Thun - Chillon) with 8 divisions. This meant that one division
was required to hold 30 kms (with 7 batallions on the frontline roughly 4 km per
batallion). Gonard considered this to be insufficent and looked at some
possibilities to shorten the frontline:
- The fortresses of Sargans
and St. Maurice would need to fight alone and then destroy the communication
lines. This would reduce the task for the field army significantly. Gonard
considered, that both fortresses could fight alone as long as the rest of the
- The mountains of the St.
Gall oberland (between the lake of Constance and Sargans) would have to be
abandoned. He considered, that this would not be a big issues, since all lines
of communication through this area lead to Sargans. One option in this part of
the study would still defend the canton of Glarus, but required the defense of
a line along the Linth canal. The other option would have been to abandon the
canton of Glarus too - this seems to have been the option Gonard preferred,
since this would have left a frontline of 60 km in strong terrain. Defending
the canton of Glarus, the line of the Linth canal and the Southern end of the
lake of Zurich required a front of 120 km with a lot of vulnerable points in
- Gonard considered the
defense of the Napf area to be too difficult with no significant gain to the
redoubt position. In addition such a defense would have asked for an extension
of the lines East and West of the Napf region to avoid the danger of enemy
encircling movements. Gonard looked at three variants and preferred the
minimal solution: to abandon the Napf area as well as the towns of Lucerne and
Thun since this still secured the Brünig pass, although the communications
with the defense of the valley of Uri was very limited.
- The question of the
independent defense of the St. Maurice area Gonard opted for the longer front
(110 instead of 45 km) which integrated the strong fortress. Looking at his
arguments it is not clear to me how important the fact was, that this solution
would defend a considerable part of the French speaking part of Switzerland
(the alps of the canton of Vaud) or how if the military considerations really
outweighted the political ones (N.B. Gonard and Guisan both lived in the
French speaking part of Switzerland).
- The plans for the defense
of the Southern front were not changed by Gonard. One of the main
considerations was the need to improve the defense of the Gletsch area (North
of the Gotthard pass), since the decision to abandon the communication between
Lucerne and Thun through the Napf area would leave this area as to be the main
communication node between the different areas of the redoubt.
here for a large version - opens a new window)
One of the key points of
Gonard's considerations is, that the central redoubt consisted of several
compartments (Bernese Oberland, Uri, Unterwalden, Glarus, Vorderrhein, Ticino,
etc) with limited means of communications between them. In Winter it would have
been difficult, if not impossible, to move supplies and troops between some of
the compartments. This compartimization would inhibit the formation of a army
reserve and would require to put all reserves to the corps and battle groups
defending the individual compartments.
Gonard wanted to take back the
territorial units attached to the border defenses to strengthen the redoubt. On
the other hand he stated, that the number of troops in the redoubt would be
limited by the amount of supplies which could be stored. It would have been
important to reduce non-combatant units to a minimum.
Study, 1. July 1940
(Col Strüby, Under Chief
of Staff Front)
The sub-chief of the front section
(Unterstabschef Front) also submitted a study on 1. July 1940. Besides of the
undisputed use of the border troops to cover the mobilization of the field army,
the study proposed three different options to the defense:
1) Defense of the actual army
position (Operations oder
2) Defense of the central redoubt (Réduit).
3) Defense of parts of the actual front and of the central redoubt at the same
The study assumed, that
"Die Schweiz wird bei den gegenwärtigen
Verhältnissen nur dann von einem direkten Angriff Deutschlands verschont werden,
wenn die Berechnungen des deutschen Generalstabses ergeben, dass der Kampf gegen
uns langwierig und zäh wird und die Schaffung eines neuen Unruheherdes im
Zentrum Europas auf längere Zeit sich ungünstig auf die deutschen Pläne
The assessment of the different options was the
- Despite the good state of the defensive
preparations (fortifications, depots etc), this position had a front which was
too long (280 km) to be held with the available forces.
- To defend a front of 185 kms was considered to
be feasible, especially since the entrances to the central redoubt would have
been small and easy to hold. But the following issues were identified:
- The border troops would have been
sacrificed with leaving an empty space of almost 100 kms depth behind them.
- Almost 3/4 of the country would have been
- To leave the strong positions (especially in
the North) was considered to create psychological problems.
- This option was considered the best, since it
shortened the front by using the strong fortifications of the old army
