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, 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
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.
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.
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.
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.
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.
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 from the Swedish capital, Stockholm. This daring maneuvre decided the outcome of the war.
Napoleon's invasion of Russia in 1812 resulted in retreat in the face of winter with the majority of the French army succumbing to frostbite and starvation, rather than combat injuries.
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.
20th century
World War I
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.
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.
