ARTILLERY PART 1:

Russian guns without recoil system

During World War 1 Russia build several fortification lines in Finland as forward defences of its capital St. Petersburg. The fortification lines needed artillery and as Russia had serious shortage modern artillery they were mostly equipped with old guns, which had no recoil systems. During Finnish Civil War of 1918 large number of these guns saw battle use with the both sides. In less then five months Finnish White Army won the Civil War capturing all the guns, which the Russian military had left behind. Another high point of use with Finnish military came during Winter War (1939 - 1940). Smaller number saw also use in Continuation War (1941 - 1944), but at that time they had been largely replaced by French guns, which were equally old-fashioned but usually in much better shape. Usually these old guns were used in secondary roles, in which they still proved useful substitutes for more modern guns, which Finnish military didn't have enough during WW2. The number of shots by the Finns with their old Russian and French made guns, which had no recoil system, may not look very substantial. But still they allowed Finnish military to save its newer guns and proved useful addition for Finnish artillery. In Winter War only about 4 % of shots were fired with guns without recoil system and in Continuation War the number was only 8,2 %.

As the title tells these guns didn't have a recoil system. Because of this the guns demanded first building well-prepared positions with ramps and recoil-effect reducing equipment before shooting with the guns could begin. Even then their rate of fire was not usually comparable to modern quick-fire artillery pieces, which had proper recoil systems. The firing rate varied from one shot per two minutes to two shots per minute, the rate-of-fire depending calibre of the gun, ammunition, training level of crew and the equipment used with the gun. Most of these old Russian guns were already in pretty sorry state when Winter War started and their ammunition was also well beyond "use-by date", this lead to much larger number of misfires than average. As if this had not been bad enough during Winter War about 40 % of the remaining ammunition were old-fashioned shrapnel, which in earlier tests had proved to be quite ineffective. Ammunition used in these guns was bagged type - meaning that gunpowder came in bags and was loaded separately from projectile and primer. So ammunition had no cartridge case of any type. Ammunition used at least with 87-mm guns had only one propellant charge size (propellant charge came in single bag), so their propellant charge size really could not be adjusted.

During Winter War some of the guns had not been equipped with wedges and other recoil dampening equipment, this partly led to these guns being with nicknames just as "Hyppyheikki" and "Hyppyjaakko" (Jumping Henry). The nicknames spread and became wide-used nicknames for all kinds of guns without recoil system within Finnish military. The stories and jokes exaggerating the "jump" caused by the recoil spread to among the Finns, in reality with the proper equipment and techniques the guns simply rolled bit backwards on their wheels and because of ramps returned back pretty much to their earlier position. When it comes to opinions of Finnish soldiers concerning these guns there seems to have been two basic lines. Finnish Military leadership and HQ's often didn't value the old guns too much and loosing few of them wasn't seen much of a loss, while rank-and-file soldiers using the guns or getting fire support from them were grateful of the little they had.

Example of typical Finnish joke concerning guns without recoil system:

Why does "hyppyheikki" need two observers?

The first observer will check where the projectile goes and the second observer will check where the gun goes.

Country of origin:

Russia, early on made in Germany for Russia.

Finnish use: Captured and used in large numbers in Finnish Civil War of 1918. Used only as training weapon in 1920's. Didn't see any use after that. Not used in WW2.

These were the smallest calibre field guns acquired by Imperial Russia in 1870's. The both versions had naturally been designed as horse-towed, but cavalry version had been intended to be more mobile by reducing its weight. This reduction of weight happened by equipping cavalry version with shorter barrel and by leaving off details like seats for the crew from top of the gun. The gun had box trail and the usual wooden wheels equipped with steel hoops. Early on German firm Krupp manufactured the gun for Russian military, but later Russian Obuhov factory became the main manufacturer. There were clear differences between the Obuhov made and Krupp made versions. Two types of breech were used in these guns: The large majority (the once made in 1893 or later) had de Bange type screw breech, while first patch of the Krupp made guns had Krupp horizontal sliding block breech (model 1873). Also two variations of elevation screw system existed and even gun barrels used by Obuhov and Krupp were structurally different: Krupp barrels had only one layer and their back part inside casing, while Obuhov barrels had two layers inside each other for the whole length of barrel. Some of the guns had gun shields, but most didn't. During World War 1 these guns were no longer among the best ones that the Russians had, but were still considered good enough for non-frontline use. Year 1918 large number of the guns had been positioned in fortifications, which the Russians had built in Finland for possible German attack.

At January of 1918 Finnish Civil War started. During the first weeks of Civil War Finnish White Army captured almost exclusively 87-mm guns such as these in its main support area of Pohjanmaa (Ostrobotnea). As a result these guns become the de facto the standard field artillery piece of Finnish White Army from until city of Tampere were captured in April of 1918. Early on also White Army had problems finding trained crews for its artillery pieces, so Artillery School was established for training them. Five out of six White Army artillery batteries formed in Artillery School and sent to front in February-March of 1918 were equipped with Russian 87-mm guns such as these. End of 1918 Finnish military had 144 of these guns in its use. Even if their number was large as it was the Civil War was the first and last war in which the Finns used them. The guns were simply too old and well worn for military use anymore. Even Suojeluskunta (Civil Guard) artillery units of 1920's and 1930's, which otherwise got certain artillery weapon models of questionable quality took none of these guns to its use. In 1920's Finnish Army used small number of them as practising weapons before most of them were scrapped and small number used in monuments. The last ones were not removed from Army warehouses until 1950's.

Finnish use: Large number captured and 12 bought from Germany in 1918. Used by Coastal Artillery and Suojeluskunta (Civil Guard) artillery before World War 2. During Winter War about 50 were used - the majority of them by coastal artillery, while few were used by two separate artillery batteries of coastal artillery. They were still used by Coastal Artillery units in 1941, but that was the last time for them being used.

At late part of 19th century the great powers spent decades trying to outdo each other in development of light field gun, which would have superior rate-of-fire. Breech loading, cartridge shot and hydraulic recoil system become the parts needed for the winning solution, but developing them took time and hard work. The first successful recoil-system didn't just appear all of the sudden with 75-mm French model 1897 (75 K/97). Several systems of varying success reducing but not removing problems created by recoil effects were introduced for artillery pieces before the final success. The Russian 87-mm artillery pieces m/1895 were among the ones equipped with these recoil-reduction systems. Basically they were the latest versions of m/1877 cannons equipped with flexing spur added in end of the box trail. As one can guess the spur-system developed by Engelhardt removed some of the worst kick of recoil, but not enough. The other improvement was simple traverse setting system allowing sideways aiming to be adjusted 4 degrees worth without moving the gun. Like usual to the era these guns had wooden wheels with steel hoops. The guns also had de Bange type screw breech, just like in Obuhov manufactured earlier m/1877, even if Obuhov doesn't seem to have manufactured this gun. The manufacturers for Finnish captured guns were St. Peterburg Metal Factory (which manufactured both versions) and Brjansk Arsenal (which didn't manufacture cavalry version). During World War 1 Russian military had brought large number of these guns to Finland. Some of the guns had gun shields.

At end of January of 1918 some of them were among the first guns, which Finnish White Army captured in Pohjanmaa region in beginning of Finnish Civil War. Along the older model 1877 versions of the same calibre they formed the backbone of Finnish White Army artillery during early part of Civil War. The German training plan for Prussian Jäger Battalion 27 also proved wise in advance: Among training guns issued to this unit of volunteered Finns seeking independence for their country were also two 87 K/95 guns and during the Civil War this experience proved very useful. Twelve guns were bought from Germany during the Civil War, but much larger numbers were captured from Russian military stocks in Helsinki and Viipuri. According one source the total number of 87 K/95 and 87 K/95-R guns captured in 1918 was only 24, but the information doesn't seem to be correct. The Finnish military artillery piece inventory from end of November 1939 includes 47 87 K/95 and 33 87 K/95-R. The also guns saw plenty of use with Finnish military also later. Two guns were used by Finnish volunteers of Aunus Carelia expedition in 1919 in Soviet Carelia. Another four guns were sold to newly established Estonian State and were used by 2nd Battery of Finnish volunteer unit Pohjan Pojat (literally translated: Boys of North) fighting in Estonia against the Bolsheviks. After the Estonian War of liberation ended the Finnish volunteers left their four guns to the Estonians. However, the large majority of these guns still remained in Finland, where they were first given to Coastal Artillery. But soon some were transferred to Suojeluskunta (Civil Guard) artillery, which used them as training weapons until World War 2.

During Winter War (1939 - 1940) only Finnish Field Artillery units using these guns were 2nd and 5th Separate Artillery Batteries. 2nd Separate Artillery Battery with its six 87 K/95 guns fought in Carelian Isthmus. 5th Separate Artillery Battery with four 87 K/95-R guns fought well in Petsamo in Finnish Lapland, where it was the only artillery unit supporting Finnish troops in that most northern part of the frontline. Two of the guns of 5th Separate Artillery Battery were lost and recaptured twice and also one Soviet tank was destroyed with their guns. The other 32 guns used in Winter War served as two-gun strong Artillery Sections of Coastal Artillery, which fought in shores of Lake Ladoga and in Viipuri Gulf. In Viipuri/Wiborg Gulf units using these guns even managed to destroy two Soviet tanks with them. Some of the guns issued to Coastal Artillery didn't see battle use.

At 1941 the only remaining user of these guns was Coastal Artillery, which had 40 guns. 24 of them were used by Hanko/Hango Detachment, while Coastal Brigades had 16. Their last shots in combat were fired in December of 1941. After 2nd World War 48 guns still remained, but most of them were soon scrapped. From historical point of view the scrapping process proved to be too thorough - none of these guns survived for museum use.

Finnish use: Large number captured in 1918, but only 3 used by Finnish White Army in Civil War. Very little use before World War 2. During Winter War some 80 guns in coastal defence use. Last shots fired in March of 1940. Not used in Continuation War. The gun had equipment only for direct-fire use.

This was the battery gun aka field artillery version of the Russian 107-mm cannon m/1877. Krupp designed and manufactured the gun for Imperial Russia. But later also Obuhov factory in Russia manufactured it. Use of the guns were limited by lack of equipment needed for indirect fire - the Russian gun-sight used with them was suitable only to direct fire. Because of this during World War 1 Russian military usually issued the gun only as direct fire guns of siege artillery (namely: typically to coastal defence in such positions, which allowed the guns to shoot direct fire for defending harbours and beaches). The gun Krupp model 1873 horizontal sliding block breech typical to Russian field guns of this era, wooden wheels with steel hoops and box trail.

Finnish White Army captured 102 of these guns in 1918. Some of them were captured already in end of January, but White Army took used only 3 of the guns during Finnish Civil War. To be more exact: 2nd Carelian Artillery Battery used those 3 guns. During the peacetime in between Finnish Civil War and Winter War the guns saw only some occasional use. Some 80 guns were used in Winter War. January 1940 some 30 guns were issued to Finnish units in Carelian Isthmus for direct fire use. Most of these 30 guns were issued to infantry units, which proved to be a mistake: Infantry lacked any training for using them, so they often left the guns unused. The other 50 guns had been issued to coastal defence units. During Winter War both the guns and their ammunition were already in very bad shape and the amount of fuses, which could be used with their ammunition was very small. The last battles in which the guns took part were in Viipuri/Wiborg Gulf in March of 1940, three Finnish artillery sections armed with these guns took part to those battles:

Because of errors made in ammunition supply from those three artillery batteries taking part to Viipurinlahti Gulf battles only one had fuses. This resulted the situation in which the other two batteries were able to participate only as spectators and due to this also two of the guns were lost. Due of their limitations these guns quite likely were the most outdated of all artillery pieces used by Finnish Army in World War 2. None were used during Continuation War.

Finnish use: Several dozen captured in 1918, but only three used by White Army in Finnish Civil War. 10 guns used in Winter War and 20 guns used in Continuation War. Last shots fired in March of 1942, not used after that.


107 millimetres was the calibre artillery of Imperial Russia had selected for medium guns. When it came to model 1877 guns of this calibre, there were two versions: Heavy siege gun version and field gun version (aka battery gun), this gun is the siege gun version. The gun is easy to identify from its high gun carriage and long barrel. Like usual the wheels had been made from wood and were with steel hoops. The guns also had the usual box trail and Krupp model 1873 horizontal sliding block breech. Obuhov factory seems to have been the sole manufacturer of this gun.

Finnish White Army captured either 46 or 57 of these guns (number varies depending source). The first ones were captured already in Pohjanmaa in end of January. Only three guns saw use in Finnish White Army, they were used by 2nd Heavy Artillery Battery (also later in war known as "2nd Artillery Battery of Carelia") established in Pietarsaari Artillery School. The artillery battery was sent to frontline in end of March and took part to battles fought in Carelian Isthmus until end of the Finnish Civil War. Most guns (29) were captured in Helsinki and the rest in Viipuri. During the years of peace after the Civil War these guns saw very little use.

However quite a larger number of these guns was used first in Winter War and later also in Continuation War. Large amount ammunition was still in warehouses when Winter War started, but typically the guns were seriously worn out, which decreased their usefulness. Ten guns were used during Winter War. Four of them were used in Carelian Isthmus by Heavy Artillery Battalion 3, which after breakthrough in Summa had to leave two of the guns to Soviets (later during Continuation War one of the two lost guns was captured back). Four guns were used in Coastal Defence of Lake Ladoga and another two guns saw use with tractor-towed artillery section in northern shore of Lake Ladoga. During Interim Peace between Winter War and Continuation War 20 guns were issued to Fortification Artillery Battalion 5 in Salpa-line.

During Continuation War (1941 - 1944) 38 guns were used. Twenty guns were briefly used by Fortification Artillery Battalion 2 supporting 14th Division, but the guns proved too heavy and difficult to keep up in that area of operations, which had only very few small roads of poor quality, so they were returned after less then a month of use. During Continuation War the main user of these guns was Fortification Artillery Battalion 6, which had mission to shoot with the guns as long as they were still useful and ammunition remained. The unit did just this in Kiestinki - Louhi sector of the front until the remaining guns became finally too worn-out to be used in March of 1942. That was the last time these guns were used in battle.

Finnish use: Large number captured in 1918, but none used by Finnish White Army in Finnish Civil War of 1918. Used as training weapons until early-mid 1920's. 12 guns used in Winter War and 23 in Continuation War. Last shots in Finnish use fired in June of 1944, not used after that.

Imperial Russian military had two versions of 152-millimetre siege gun m/1877 and this was one of them. Russians separated the two versions according weight of their barrel using Russian unit of weight measurement "pud", which was about 16.38 kg. So, basically this 120-pud version had notably shorter barrel, than the other (190-pud) version. The gun had box-trail, wooden wheels with steel hoops and horizontal sliding block breech typical to large calibre Russian siege guns of the era. The trail used included also primitive recoil reduction mechanism. It seems that Obuhov and Perm factories were only manufacturers of these guns.

Finnish White Army captured 102 of these guns in 1918, but used none in the Finnish Civil War. Immediately after the Civil War six of these guns were issued to three artillery batteries (with 2 guns each), which were created to Äyräpää, Metsäpirtti and Sakkola near the border in Carelian Isthmus. The artillery batteries were to be crewed by local Suojeluskunta (Civil Guard) units if needed and existed until year 1921. The guns were also used as training equipment in Heavy Artillery Regiment until early - mid 1920's.

During Winter War 12 guns were used by Heavy Artillery Battalion 5. Later during Continuation War they saw some use with Syväri Fortification Artillery Battalion 1. When Finnish troops retreated from river Syväri/Svir the Fortification Artillery in June of 1944 Battalion still had 23 of these guns. As the guns were so worn-out, outdated and difficult to transport Finnish troops left them behind. Finnish military found these old guns to be accurate and their projectiles powerful, but transporting guns this heavy proved problematic.

Finnish use: Only four guns captured in 1918. Two of the guns used by Finnish White Army in Civil War. During Winter War guns used by Ladoga Coastal Defence. In Continuation War used by Fortification Artillery and Coastal Artillery. Last shots fired in Finnish use in June of 1944, not used after that.

This was the last, heaviest and most modern of Russian 152-mm siege guns. The gun was manufactured by Russian Obuhov factory and unlike earlier heavy siege guns had de Bange screw breech. The wheels were the usual ones with steel hoops and the gun also had the usual box trail, but the gun also had in-built system which somewhat reduced its recoil. The recoil reduction system related to ones used in Russian heavy mortars at that time and used a hydraulic axle anchored to ground for dampening the recoil.

The gun was also one of the rarest gun models captured by Finnish White Army in 1918 as only four were captured. Those 4 guns were captured in beginning of Civil War in Kaskinen, but first transporting them caused a problem. However as heavier artillery was needed two of the guns were issued to 1st Finnish Heavy Artillery Battery established in end of February. After training of just two weeks the newly established artillery unit was sent to frontline where it arrived to Vilppula sector in 13th of March. The unit nicknamed its two guns as "Ukko" (= cogler) and "Akka" (= hag). After battles of Vilppula front the unit also took part to capture of Tampere. For obvious reasons Finnish Heavy Artillery Battery was one of the very few Finnish White Army units in Finnish Civil War to rely using indirect fire and was never used for direct-fire missions.

All the four guns were later used both in Winter War and Continuation War. In Winter War they were issued to Coastal Defence of Lake Ladoga, which used them to give fire support against Soviets in Kitilä motti and also in battle of Koirinoja. During Interim Peace between Winter War and Continuation War the four guns were issued to Fortification Artillery Battalion 1 of Salpa-line. When Continuation War broke out the same unit first continued using the guns. Later they were transferred to 3rd Artillery Battalion of Coastal Artillery Regiment 13 and Ladoga Coastal Brigade in northern shore of Lake Ladoga. In hands of Ladoga Coastal Brigade the guns fired their last shots in battle of Tuulos in June of 1944. Two of the four guns were lost in that battle. The two remaining guns are in Finnish museums.

Finnish use: 6 captured in 1918, but not used in Civil War. Four installed to Salpa-line around 1940 - 1941, but not used in battle. One transported to Syväri/Svir front in August of 1942, it was used in battle until June of 1944.

This was 9-inch Russian coastal mortar model 1877. As the mortar was designed for coastal forts, it was anything but mobile. Six (presumably) mortars were captured in 1918, but the Finns didn't find them any use until first phase of constructing fortified Salpa-line after Winter War. During Interim Peace of 1940 - 1941 four of the mortars were installed to fortified artillery positions build to give fire support for defenders of Salpa-line. The mortars were issued to Fortification Artillery Battalion 4, but they didn't saw any battle use as Soviets never managed to reach Salpa-Line. Summer of 1942 one mortar was placed to fortified artillery position build to Syväri/Svir sector of frontline. Starting from August of 1942 this mortar issued to Syväri Fortification Artillery Battalion 1 shelled the Soviets every now and then. The mortar crew named the weapon as "Rymy-Eetu" after popular figure of propaganda cartoon. When Finnish troops retreated from river Syväri/Svir in June of 1944 the mortar, which had spent all its ammunition was left behind. By that time it had fired 241 shots. The "Rymy-Eetu" mortar was largest calibre artillery piece used in battle by Finnish Fortification artillery in World War.

OTHER OLD RUSSIAN ARTILLERY PIECES WITHOUT RECOIL SYSTEM:

152 K/77-190p (152-mm cannon model 1877, 190-pud barrel version): This was the other version of 152-mm Russian m/1877 siege gun - the version with slightly longer and considerably heavier barrel. These two versions had been named according barrel weight, which was expressed in Russian weight measurement "pud" (about 16.38 kg). As usual the gun had box trail and wooden wheels with steel hoops. The gun also had somewhat ineffective in-built recoil reduction system. 115 guns were captured in 1918, but the Finns never used any in battle. Russian Obuhov and Perm factories had manufactured all of these captured guns. The 120-pud barrel version not only had better range because of more modern projectiles, but it also was handier and weighted less, so Finnish military favoured it instead of this 190-pud barrel version.

PICTURE: 152 K/77-190p with breech block missing. The 120-pud version looked quite similar, but had slightly slimmer barrel. (Photo taken in Tykistömuseo). CLICK THUMBNAIL TO SEE LARGER PIC (58 KB).

279 M/77 (279-mm mortar model 1877): This was Russian 11-inch coastal mortar. Just like its 9-inch cousin it was designed for coastal fortresses and moving one to another fire position demanded laboured process of first dismantling the mortar and its fortification carriage and then assembling it again in new position. The mortar had wedge-block breech. Four or five of these mortars were captured in 1918, but they didn't saw any use until finally 4 were installed to fortified artillery positions of Salpa-line and issued to Fortification Artillery Battalion 1. Even then they didn't see any battle use and already in 1945 three were scrapped. The only remaining mortar is nowadays in Suomenlinna.
