Lessons from the Great War - Trench warfare developments in Swedish army during the WWI . Part VII. Officers course in trench warfare

In the same period as the SGS during the autumn of 1916 proposed several measures to be conducted for the army regarding trench warfare there was also a proposal for an officer-course. The aim of the course was to educate officers in usage of hand grenades, mortars, infantry shields and other technical equipment and also about filed fortifications works and cooperation between infantry and artillery during attack and defence.[1] The course later decided to be performed during two weeks in October of 1917. The officers came mainly from the infantry and engineer units while others came from the artillery and Royal Fortification.[2] According to the course plan the main effort was placed on attack combat. Officers were even trained how to perform in a storm patrol (stormpatrull) which meant that the stormtroopers tactic was a part of the course. The course commander, Lt Col Gustaf Lillehöök who also was the chief of the Royal War Academy, was studying the stormtroopers in May of 1917 in the German and Austro-Hungarian army.

According to the report that was written after the course a conclusion can be made that the Swedish army had the latest knowledge regarding trench warfare. In one of the lectures during the course it was mentioned that trench warfare was a result consisting of development in military technology and the sizes of the armies, especially of the Great Powers. Also, it was mentioned about the risks of presuming or believing that mobile warfare had lost its importance. The developments of the war had shown that a breakthrough and mobile warfare still could be achieved.  It was also mentioned that a long term positional war in Sweden was unlikely because of the geographical reasons and political situation. It meant that Sweden was unlikely to be attacked since its neutral position and that the long borders and areas of the country meant that long lines of trenches were hard to achieve both for the attacker and defender.[3] In the end, mobile warfare was according to lecture still a necessity in the case of war.

The course meant that the knowledge in the SGS was on a very high level since it was based on the latest experiences mainly from the central powers. But when it comes to knowledge about trench warfare among the army’s officers corps it is doubtful that the level of knowledge could be considered high. Lilliehööks own opinion was that the length of the course was not enough for a deeper education. It was instead more an orientation of the latest experiences.

Lessons from the Great War - Trench warfare developments in Swedish army during the WWI . Part VI. Exercises in trench warfare

General Staff’s field service exercise in 1916

During the beginning of October 1916, a field service exercise took pace in area between Stockholm and Uppsala.[1] Comparing with the Fortification exercise from 1915, these exercises was not mainly based on trench warfare. It was rather organized for exercising attack on and defence of rapidly established entrenched positions.[2] A scenario for the exercise was based on combat between two fictive armies. Units that performed the attack on the first day of the exercises noted that the first attacking flank did not succeed because they did not use artillery while the second flank did the opposite and performed a successful attack.[3] Also, the troops where for the first time using a contemporary weapon system which was developed for trench warfare – mortar.

The commander of the engineer troops wrote in his report that the filed works were used in greater and better way compared with earlier exercises in order to meet the modern necessity and the ongoing inevitable experiences.[4] But also he wrote some negative criticism, among other things that establishment of filed fortifications often was not performed in a professional way. The troops were according to report in many cases not performing in a realistic and professional way.[5] Form the report a conclusion can be made that the Swedish army units still lacked basic knowledge about trench warfare combat.


Exercises in trench warfare during the summer of 1917

At the same time as the proposal for instruction for trench warfare was published the exercises in trench warfare were to be held. Concept for the exercises was based on using the proposal for instruction in order to exercise establishment of two fortified positions with two companies against each other. The companies were supported by machineguns and with either fictive or real artillery.[6] By that way exercises were held on company and battalion level. The duration of the exercises was around 10-12 days and they were divided in two periods. The first period was based on establishing the positions and the second period was based on exercising trench combat.


The troops were also using special weapons and systems that were particular for trench warfare: signal-pistols, hand grenades, trench mortars and wire cutters. The commanders were trained to give orders and to lead the troops during attack and defence. Also, requirements were imposed on NCO: s to use the initiative during counter-attacks.[7]

During the exercises several problems were identified. The trench works were in several cases perceived to have been established on inappropriate places and as unfinished before combat training started.[8] Many commanders lacked practical training and experience regarding trench warfare as they only had theoretical training which limited their ability to lead. The troops were in many cases performing in inadequate ways as they were not supposed to do in reality.[9] Experiences from exercises were gathered, written down and later sent to SGS.

Proposals for instruction and exercises in trench warfare

In 1916 at the end of September Chief of General Staff Knut Bildt made a statement to the Land defence ministry regarding the needed funds for exercises where he wrote that:

Experiences from the World War are putting importance on that the troops are familiar with construction and establishment of fortified positions, that they are trained for attack on and defence of those positions, and that they understand how to manage their own ability to act in the positions and in front of them by the most practical and energy-saving way.[1]

According to the statement, it was of great importance that exercises in trench warfare already could be performed among a number of regiments during the conscription period of 1916-1917. Bildt also proposed that as a ground for exercise a proposal for instruction for trench warfare should be worked out. According to Bildt, the war had clearly shown the importance of trench warfare and the need for modern regulation for combat training. Now there was a formal call to replace the draft proposal for attack against fortifications from 1914. Bildt also proposed that this assignment was to be given to Tingsten and a number of experts.[2]

Later Tingsten informed Bildt that he agreed upon his statement and also proposed that the experts should be Bouveng, Hamamrsköld and Captain Kaijser from the Fortification since according to Tingsten all of these have studied the relevant conditions during this ongoing war.[3] In the beginning of December Tingsten and his experts were approved by the Land defence ministry.[4] 


                        Proposal for instruction for trench warfare. 






We could not base us after the German Western front

When the proposal for instruction was approved, published and delivered to the units in June of 1917 it was based on the experiences gathered from the German army on the Eastern front. By that time the German army had changed its tactics and strategy for trench warfare. On the Western front the German army had introduced the so-called Elastic defence or Zonal defence where defence zones replaced the system with defence lines. At the same time the German Stormtrupptaktik or Stosstrupptaktik (Stormtrooper tactic) became a formal tactic within the army and was used mainly on the Eastern front. SGS had information about these developments in the German army and at the same time, the proposal for instruction was based on experience that now were seen as outdated and abandoned because of high casualties since the first line was to be defended at all cost. There also was nothing mentioned about stormtroopers in the proposal.  


According to Tingstens memories, he and the experts came to the conclusion that they could not base the proposal for instruction on the German Western front.[5] Already two months after proposal was published Tingsten wrote in an article which was published in Krigsvetenskapsakademiens tidskrift  (Royal War Academy Journal) that positional warfare hardly […] was desirable for a small nation with long borders. According to Tinsgten the fronts would become too long compared to the number which would sooner or later lead to disaster.


Another view on this topic was made by Bouveng who also published a text in Krigsvetenskapsakademiens handlingar (Royal War Academy Record) in 1917. According to him, the development based on an enormous concentration of troops and artillery on the Western front was an exception. For Swedish concerns, more general conclusions should be taken from the Eastern front, especially regarding the interaction between the mobile war and positional war.[6]


Both Tingsten and Bouveng shared the view that in case of war the Western front scenario was probably not a realistic scenario for waging war in Sweden. Reasons for that was that resources for several months of positional warfare were insufficient and that Sweden as a country with long borders was too big to defend by long lines of trenches. The difference was that Bouveng was proposing interaction between two kinds of warfare that took place during the WWI while Tingsten is in Swedish military history research considered to have been a proponent of the pre-WWI mobile warfare with encountering combat. Also, the much greater interest for the Swedish army during WWI was the Eastern front probably due to the general view that Tsarist Russia was the main potential enemy in case of war.[7]



Quite good and the best  for  the moment that was  able to be achieved

In his statement regarding the proposal for instruction before it was published Bildt concluded that it was not possible to have a clef opinions about some issues since experiences from the war were not entirely known.[8] There was neither any experience in the Swedish army about usage of the basic tactics in positional warfare since there had not been any exercises.



Characteristics of the proposal for instruction for trench warfare

During a long time, a defence area was supposed to have consisted of one position that was called main position. If there was better time possibilities also one or two more positions in the back would be established. The distance between the main position and first position in the back would be of that size so that attacker’s artillery could not fire on both. The main defence combat was to be performed in the main position while the positions in the back where to be used as reserve for defence if the main position was needed to be abandoned. Also between the main position and the back position the so-called fixed points as bunkers and machine-gun nests were to be established in order to slow down or stop the advancement of the attacking troops.[9]


The main poison was supposed to consist of three parallel defence lines that were connected with communication trenches. The first line was the main defence line while the other two were reserve lines. Also according to the proposal, the defence was to be performed in combination with the attack. If the first defence line was overrun the reserves from the other two were supposed to perform a counterattack and if that was not enough then the reserves from the back positions would also perform the counterattack.[10] Proposal maintained the values of cooperation between artillery, infantry and engineer troops.[11]

During the attacker’s artillery preparations the defenders' artillery was in cooperation with aeroplanes supposed to engage the attacker’s artillery. During the attack, the defence artillery was supposed to fire frontal fire or flanking fire called spare fire (spärreld on Swedish from the German term speerfeur) which was planned in beforehand.[12]

During the attack, the assignments of artillery were to initially engage enemy’s artillery and in later stage to support the attacking infantry by engaging barbed wire, machine guns nests, observations posts etc. During the final attack, the fire would be directed behind the defenders' main defence line in order to prevent reserves from reinforcing or performing a counterattack. Also, a part of artillery would still engage the enemy’s artillery.[13]

On the infantry side, the attacking force would be divided into storming columns where the first troops would advance in several dense formatted firing lines.[14] Also among the first advancing troops' engineers would participate in order to counter different types of obstacles. Proposal also put importance on the initiative among squad leaders and others commanders on the place who were supposed to lead their units on their own if a greater result during the attack could be achieved.[15]During the defence the infantry was supposed to take cover in the shelters during the attacker’s artillery fire and to leave the shelters in order to defend the position only after the attacker’s fire had been ceased.
