United Kingdom Royal Marine reservists training for winter operations in Norway in 2014

Cold-weather warfare, also known as arctic warfare or winter warfare, encompasses military operations affected by snow, ice, thawing conditions, or cold, both on land and at sea, as well as the strategies and tactics used by military forces in these situations and environments.

Cold-weather conditions occur year-round at high elevation or latitudes, and elsewhere materialize seasonally during the winter period. Mountain warfare often takes place in cold weather or on terrain that is affected by ice and snow, such as the Alps and the Himalayas. Historically, most such operations have been during winter in the Northern Hemisphere. Some have occurred above the Arctic Circle where snow, ice, and cold may occur throughout the year.

At times, cold—or its aftermath, thaw—has been a decisive factor in the failure of a campaign, as with the French invasion of Russia in 1812, the Soviet invasion of Finland in 1939,[1][2] and the German invasion of the Soviet Union during World War II.

History

Northern and Eastern Europe were the venues for some well-documented winter campaigns. During World War II several actions took place above the Arctic Circle. Recent cold-weather conflicts have occurred in the Himalayas.

Pre–1800

The 1658 March Across the Belts in the Second Northern War

In 1242, the Teutonic Order lost the Battle on the Ice on Lake Peipus to Novgorod. In 1520, the decisive Battle of Bogesund between Sweden and Denmark occurred on the ice of lake Åsunden.[3]

In 1643 or 1644, Prince Rupert made an abortive attack on the Parliamentarian stronghold of Aylesbury England. 500 men are reported to have frozen to death on 21 January. On 25 January a sudden thaw caused a bridge to collapse over the River Weaver, splitting Royalist cavalry forces at the Battle of Nantwich resulting in their defeat.[4]

The 1557 Siege of Katsurayama was fought between the forces of the Japanese daimyō Takeda Shingen and Uesugi Kenshin as part of the Kawanakajima campaigns. Katsurayama castle was a strategically vital Uesugi stronghold in the contested Shinano Province and, when it was isolated from reinforcements due to late snow in early 1557, the Takeda clan used this opportunity to seize it under Baba Nobuharu, shielded from view by heavy snowfall.[5]

Sweden and Denmark fought several wars during the 16th and 17th centuries. As a great deal of Denmark consists of islands, it was usually safe from invasion, but in January 1658, most of the Danish waters froze. Charles X Gustav of Sweden led his army across the ice of the Belts to besiege Copenhagen. The war ended with the treaty of Roskilde, a treaty very favorable to the Swedish.[6]

During the Great Northern War, Swedish king Charles XII set off to invade Moscow, but was eventually defeated at the Battle of Poltava after being weakened by cold weather and scorched earth tactics. Sweden suffered more casualties during the same war as Carl Gustaf Armfeldt with 6,000 men tried to invade Trondheim. Three thousand of them died of exposure in the snow during the Carolean Death March.[7]

19th century

During the Finnish War, the Russian army unexpectedly crossed the frozen Gulf of Bothnia from Finland to Åland and, by 19 March 1809, reached the Swedish shore within 70 kilometres (43 mi) from the Swedish capital, Stockholm. This daring maneuvre decided the outcome of the war.[8]

Napoleon's invasion of Russia in 1812 resulted in retreat in the face of winter[9] with the majority of the French army succumbing to frostbite and starvation, rather than combat injuries.[10]

The Battle of Weihaiwei was a battle of the First Sino-Japanese War in the winter of 1895 in Weihai, Shandong, China between the forces of the Japan and Qing China. Through a well coordinated offensive of both naval and land forces, hampered by snow and cold, the Japanese destroyed the forts on shore and sank much of the Chinese fleet.[11]

20th century

World War I

Italian mountain troops in WWI

During the First World War, soldiers on the Western front involved in trench warfare were forced to deal with freezing conditions, trench foot, frostbite, and disease. The winter of 1916-17 was exceptionally cold, which caused great hardship and deaths among the soldiers. Equipment and vehicles also were not suited for the freezing conditions.[12]

At the Battle of Sarikamish, Ottoman troops were unprepared for winter fighting and suffered major losses, with 25,000 freezing to death before the battle even began.

On the Italian front, fighting bogged down in trench warfare but at mountain elevations. On White Friday, thousands of troops from both sides were killed in avalanches in the Dolomites.

World War II

Finnish ski troops during the 1939 Winter War

The Finnish Army used ski troops during the Winter War and the Second World War in which the numerically-superior but road-bound Soviet forces were vulnerable to attack by mobile, white-clad ski troops, approaching from untracked, frozen terrain.[13]

The Wehrmacht maintained elite mountain troops, Gebirgsjäger. They were organized in small, specialized units, which relied on pack animals. Typical weapons were light machine guns, mortars, and anti-tank guns. Control of ridge lines was paramount, using a limited number of outposts.[14] They operated on the principles of fewer arms, but more ammunition per weapon and the economical use thereof.[15]

In Operation Barbarossa in 1941, both Russian and German soldiers had to endure terrible conditions during the Russian winter. The German-Finnish joint offensive against Murmansk (Operation Silver Fox) in 1941 saw heavy fighting in the Arctic environment. Subsequently, the Petsamo-Kirkenes Operation conducted by the Soviet Army against the Wehrmacht in 1944 in northern Finland and Norway drove the Germans out.[16] In late 1944, Finland turned against its former cobelligerents of Nazi Germany under Soviet pressure and pressured the Germans to withdraw in the ensuing Lapland War.[17] While use of ski infantry was common in the Soviet Army, Germany formed only one division for movement on skis.[13] From June 1942 to August 1943, the United States and Canada fought the Japanese in the Aleutian Islands Campaign in the Alaska Territory.[18]

In the Arctic

The following actions were fought in the Arctic by land and naval forces in World War II between 1941 and 1945 in the following theaters of operations:

Finland – The Winter War was a military conflict between the Soviet Union (USSR) and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940.

In the Battle of Suomussalmi, Finns leveraged cold weather to disadvantage the Soviet enemy troops by targeting field kitchens and campfires for their attacks, thereby denying those troops warmth and nutrition.[19][20] The Finns rotated their troops so that they could regularly return to warm shelters to recuperate after an attack or patrol. Heavy Soviet equipment and their associated troops were restricted to roads, while Finnish ski troops had broad mobility to outflank the enemy.[20] The threat of Finnish snipers, whom the Russians called "cuckoos", further demoralized the Soviets.[19][20] The Finns mined ice routes over lakes to sink Soviet equipment.[21]

The Lapland War was fought between Finland and Germany from September 1944 to April 1945 in Finland's northernmost Lapland Province. It included:[22]

Norway – The liberation of Finnmark was a military operation, lasting from 23 October 1944 until 26 April 1945, in which Soviet and Norwegian forces wrestled away control of Finnmark, the northernmost county of Norway, from Germany. It started with a major Soviet offensive that liberated Kirkenes.[26]

Northern RussiaOperation Silver Fox was a joint German–Finnish military operation offensive during World War II. It failed to achieve its main goal to cut off and ultimately capture the key Soviet port at Murmansk through attacks from Finnish and Norwegian territory.[27]

SpitsbergenOperation Gauntlet was a Combined Operations raid by Canadian troops, with British Army logistics support and Free Norwegian Forces servicemen on the Norwegian island of Spitsbergen, 600 miles (970 km) south of the North Pole, from 25 August to 3 September 1941.[28] Operation Fritham was a Norwegian military operation, based from British soil, that had the goal of securing the rich coal mines on the island of Spitsbergen (a part of Svalbard) and denying their use to Nazi Germany.[29] Operation Zitronella (Citronella) was an eight-hour German raid on Spitzbergen on 8 September 1943.[30] This marks the highest latitude at which a land battle has ever been fought. However, given the extreme conditions, the German and Allied troops were at times compelled to assist each other to survive.[31]

United States – The Aleutian Islands Campaign was a campaign conducted by both the United States and Imperial Japan from 3 June 1942 to 15 August 1943 in Attu and Kiska, part of the Aleutian Islands in Alaska during World War II.[32]

Post World War II

Comparison of Chinese and U.S. military winter field uniforms, 1951

The Battle of Chosin Reservoir was a stark example of cold affecting military operations in the Korean War. There were many cold injuries and malfunctions of materiel, both vehicles and weapons.[33][34]

The Sino-Indian War was a Himalayan border conflict between China and India that occurred in 1962. India initiated a Forward Policy in which it placed outposts along the border in 1961. China launched simultaneous offensives in Ladakh and across the McMahon Line on 20 October 1962. Chinese troops advanced over Indian forces in both theaters. Much of the fighting took place in harsh mountain conditions, entailing large-scale combat at altitudes of over 4,000 metres (14,000 feet).[35] Many troops on both sides succumbed to the freezing cold temperatures.[36]

Argentine troops suffered from cold-wet conditions, holding positions in the 1982 Falklands War.[37]

The Siachen conflict is a military confrontation between India and Pakistan over the disputed Siachen Glacier region in Kashmir. The conflict began in 1984 with India's successful Operation Meghdoot during which it gained control over all of the Siachen Glacier.[38] A cease-fire went into effect in 2003.[39]

Historical lessons learned

Paton offered a 2001 overview of human factors pertaining to cold in military operations. The understanding of cold injuries evolved in the 19th and 20th centuries; understanding of the causes and treatment of frostbite and trench foot improved. In the Sino-Japanese War, the Japanese learned the importance of foot care, keeping feet dry and warm with replacement socks. In World War I, doctors realized that trench foot was a prolonged exposure to cold, wet conditions on the feet, which were exacerbated by the use of tight puttees, bandage-like leg wrappings.[40]

The Soviet invasion of Finland during the Winter War showed the power of asymmetric warfare on the Finnish side, where small units were able to cut the road-bound Soviet invading troops into segments, like firewood, and vanquish each segment. The small units arrived silently on skis or with light artillery pulled by reindeer over frozen, untracked terrain, using winter conditions as an advantage. Although the Soviet Union gained territory from the Finns, it was at the cost of 200,000 fatalities against 25,000 on the Finnish side.[2]

The German invasion of the Soviet Union induced more than 250,000 cold injuries in one year. The French Army occupying the Maginot Line experienced 12,000 cold injuries. Experiences from the disastrous 1941 German advance on Moscow in winter conditions led to the 1942 Taschenbuch für den Winterkrieg ("Pocket book for Winter War"), which highlighted ideal approaches to handling winter, but acknowledged that improvisation in the field would be necessary when supplies were lacking. The Soviet troops in that period had felt-lined boots and quilted uniforms, but the Germans continued fighting in their summer uniforms.[40]

German handbook

The Taschenbuch für den Winterkrieg manual contains sections on the influence and duration of winter, the seasons of mud and thaw, preparation for winter warfare, winter combat methods and maintaining morale, including the use of reading material, lectures, movies, and "strength through joy" exercises. Other sections cover marches, the maintenance of roads, winter bivouacs and shelter, construction of winter positions, camouflage and concealment, identification of the enemy, clothing, rations, evacuation of the wounded, care and use of weapons and equipment, signal communication, and winter mobility. The manual was designed to provide information at the officer level for indoctrination of troops via the non-commissioned officer ranks. The scope of the manual is to train troops in the following areas:[41]

  • Protection of personnel, vehicles and weapons against snow and cold
  • Training personnel to be hardened against the conditions encountered and able to improvise shelter from found materials
  • Mobility on skis, winter roads, ice crossings, and conversion of wheeled vehicles into tracked versions
  • Construction of positions and obstacles in frozen terrain
  • Combat in deep snow and severe cold

Some highlights include addressing:[41]

  • Human factors – Providing the right level of clothing to maintain agility and avoid overheating. Maintaining a slow, steady marching pace to avoid chilling down in the wind. Boosting morale with up-to-date newspapers from home and nearby areas. Providing improvised shelters and bivouacs. Hygiene, emphasizing cleanliness.
  • Mobility – Setting up and maintaining winter roads and trails. Warming up engines for reliable starting.
  • Positions and fortifications – Using logs and snow as materials to provide trenches and gun emplacements.
  • Care of equipment – Keeping equipment dry, when possible, and substituting low-temperature lubricants for oils and hydraulic fluids.

Soviet experience

The Soviet Army learned from its 1939–40 Winter War experiences and the 1941 German advance on Moscow. The high command realized that it must prepare entire divisions for winter warfare in 1942, beginning with warm uniforms, winter equipment (skis, etc.), and training for winter operations. Analysis of previous experiences resulted in a series of manuals that covered flight, engineer, and combat arms operations in winter. Issues covered included:[42]

  • Flight operations – Reduced daylight, snow drifting, cold temperatures impeded the added need for air transport.
  • Engineer operations – Engineer troops build new roadways, airfields, water crossings, and encampments with water supply. They destroy obstacles, requiring engineering equipment. Regular troops entrench tanks, construct tank obstacles, and build simple shelters.
  • Combat arms operations – Addressing the German methods of defense with automatic weapons strongholds, supplemented with mines, wires, and anti-tank obstacles. Against these, the Russians used coordinated massed fire.

In his 1981 paper, Fighting the Russians in Winter: Three Case Studies, Chew draws on experiences from the Allied-Soviet War in Northern Russia during the Winter of 1918–19, the destruction of the Soviet 44th Motorized Rifle Division, and Nazi–Soviet Warfare during World War II to derive winter warfare factors pertaining to military tactics, materiel and personnel:[43]

  • Tactics – Defensive positions are highly advantageous because of the ability to maintain warmth and protection, compared to attacking in extreme cold. Mobility and logistical support are often restricted by snow, requiring plowing or compacting it to accommodate wide-tracked vehicles or sleds. Infantry movement in deep snow requires skis or snowshoes to avoid exhaustion. Sound carries well over crusted snow, diminishing the element of surprise. Explosives are useful for excavating foxholes and larger shelters in frozen ground. Attacking field kitchens and encampments deprives the enemy of food and shelter. Rapid removal of the wounded from the battlefield is essential to their survival in the cold.
  • Materiel – Weapons and vehicles require special lubricants to operate at low temperatures. Mines are unreliable in winter, owing to deep snow that may cushion the fuse or form an ice bridge over the detonator.
  • Personnel – Proper winter clothing is required to maintain body heat and to avoid such cold injuries as frostbite. Troop efficiency and survival requires either making use of available shelter or providing portable shelter.

Land operations

Operational factors encompass planning for the climate and weather in which military operations are required with snow, ice, mud and cold being the primary considerations. Military tactics, materiel, combat engineering and military medicine all require specialized adaptations to the conditions encountered in cold weather.[44]

Cold and mountainous regions

In its 2016 "Mountain Warfare and Cold Weather Operations" manual, the United States Army defines cold regions as "where cold temperatures, unique terrain, and snowfall have a significant effect on military operations for one month or more each year." It describes regions that are either severely cold or moderately cold, each comprising approximately one quarter of the Earth's land mass.[45]

  • Severely cold – Where mean annual air temperatures stay below freezing, maximum snow depths exceed 60 centimetres (24 in), and ice covers lakes and rivers for more than 180 days each year.
  • Moderately cold – Where the mean temperatures during the coldest month are below freezing.

The manual also delineates the principal mountain ranges of the world, which lie along broad belts which encircle the Pacific basin and then lead westward across Eurasia into North Africa. Secondarily, rugged chains of mountains lie along the Atlantic margins of the Americas and Europe.

Weather conditions

Temperature, wind, snow, and thaw are the primary conditions that affect the winter battlescape.

Temperature

The U.S. Army groups cold temperatures using categories. The temperature categories are (with quoted summaries):[45]

  • Wet cold – From 39 to 20 °F (4 to −7 °C). Wet cold conditions occur when wet snow and rain often accompany wet cold conditions. This type of environment is more dangerous to troops and equipment than the colder, dry cold environments because the ground becomes slushy and muddy and clothing and equipment becomes perpetually wet and damp.
  • Dry cold – From 19 to −4 °F (−7 to −20 °C). Dry cold conditions are easier to live in than wet cold conditions. Like in wet cold conditions, proper equipment, training and leadership are critical to successful operations. Wind chill is a complicating factor in this type of cold. The dry cold environment is the easiest of the four cold weather categories to survive in because of low humidity and the ground remains frozen. As a result, people and equipment are not subject to the effects of the thawing and freezing cycle, and precipitation is generally in the form of dry snow.
  • Intense cold – From −5 to −25 °F (−21 to −32 °C). This temperature range can affect the mind as much as the body. Simple tasks take longer and require more effort than in warmer temperatures and the quality of work degrades as attention-to-detail diminishes. Clothing becomes more bulky to compensate for the cold so troops lose dexterity. Commanders consider these factors when planning operations and assigning tasks.
  • Extreme cold – From −25 to −40 °F (−32 to −40 °C). In extreme cold the challenge of survival becomes paramount as personnel withdraw into themselves. Weapons, vehicles and munitions are likely to fail in this environment.
  • Hazardous cold – From −40 °F (−40 °C) and below. Units require extensive training before operating in these temperature extremes.

The combined cooling effect of ambient temperature and wind (wind chill) is an important factor that affects troops.

Snow

For military purposes, the U.S. Army categorizes snow as light, moderate, or heavy. Each classification affects visibility and ground movement due to accumulation and is quoted below:[45]

  • Light snow – Visibility is equal to or greater than 58 mile (1,000 m) in falling snow. A trace to one inch (2.5 cm) per hour accumulates.
  • Moderate snow – Visibility is 516 to 12 mile (500 to 800 m) in falling snow. One to three inches (2.5 to 7.6 cm) per hour accumulates.
  • Heavy snow – Visibility is less than 14 mile (400 m) in falling snow. Three inches (7.6 cm) or more inches per hour accumulates.

Snow and snowdrifts can create advantages on the battlefield by filling in ditches and vehicle tracks and flattening the terrain. It also creates hollows on the downwind side of obstacles, such as trees, buildings, and bushes, which provide observation points or firing positions. Snowdrifts may provide cover for soldiers to approach an objective.[45] Soviet Army doctrine cited 30 centimetres (12 in) as the threshold snow depth that impairs mobility for troops, cavalry and vehicles, except tanks for which the threshold was 50 centimetres (20 in).[42]

Thaw

Thawing conditions can impair mobility and put soldiers at risk of trench foot by turning soil to mud; it can also weaken and break up ice cover on bodies of water. Maintaining roads becomes more difficult during spring-thaw run-off periods and requires mud removal by heavy equipment. Slushy and muddy ground causes clothing and equipment to become wet, damp and dirty.[45] Muddy conditions greatly inhibited Napoleon's ability to maneuver in Russia in the autumn of 1812[46] and also the German attempt to take Moscow in the autumn of 1941.[47]

The 1942 Taschenbuch für den Winterkrieg acknowledges that neither tracked nor wheeled vehicles can maneuver during conditions of thaw and that aircraft operations must be constrained to concrete runways. It addresses minimizing the use of roads during this period and dismantling bridges that are likely to be taken out by ice floes. It emphasizes how positions in frozen soil must be improved to avoid deterioration from thaw and the necessity of changing uniforms from ones for cold to those for wet conditions.[41]

Tactics

The dominant tactical concern in cold conditions is the ability to maneuver in vehicles or on foot. Additionally, during winter, night operations become the norm at higher latitudes with their long periods of darkness.[45] Snow enhances night vision because of high reflectivity and the visibility of combatants against the white background.[42]

Mounted movement

The German Taschenbuch für den Winterkrieg emphasizes reconnaissance to ascertain the conditions and capacity of the roads to be used. It describes snow clearing from roads and recovery of bogged-down vehicles.[41]

Soviet Army doctrine emphasized the use of sleds for transporting machine guns and mortars over snow, towed in a train by tracked tractors. It addressed the need to pre-heat tanks for use in winter and their application in advance of marching troops to take out enemy positions.[42]

Finnish military doctrine calls for small-unit movements with Anti-tank guided missiles and multiple launch rocket systems to attack foreign forces that have entered the country.[2]

U.S. Army guidance advocates that over snow-covered terrain, vehicles may be employed to establish and maintain trails by establishing a well concealed track with the first vehicle, followed by a vehicle traveling offset from the track of the first, to flatten the trail, and subsequent vehicles widening and flattening the trail. Marked trails avoid obliteration in snowstorms or drifting conditions. In mountainous terrain, tracked vehicles, including tanks, infantry fighting vehicles, and cavalry fighting vehicles, rarely accompany dismounted infantry in the assault. Instead, they assist forces by occupying positions where they can use their firepower to isolate enemy objectives.[45] Zdroj:https://en.wikipedia.org?pojem=Arctic_warfare
