98-699: A follow-on derivative of the O-25 variant, an O-38 . Starting in 1926, a mailplane version of the O-2 called the M-2 entered service with Western replacing the DH-4 . The plane was successful in the route, resulting in further development of the mailplane version of the O-2. (see Douglas mailplanes ) Douglas O-2M variants were deployed by the Chinese Air Force 's 6th, 7th, and 8th Bomber-Attack and Scouting-Attack Groups in combat against

147-576: A minority of them stayed in southern China. The Chinese Red Army's weapons were all captured from the enemy army, with the most important and useful weapon being the rifle. In the winter of 1934, the First Red Army's twelve divisions had 72,300 soldiers and 25,300 rifles. Compared to the First Red Army, the Fourth Red Army had more rifles which allowed it to recruit many new soldiers in Sichuan. However,

196-707: A new group army. It was named the Second Red Army and He Long was tasked with being its commander. The Second Red Army and Fourth Red Army arrived in north Shaanxi in the autumn of 1936. Around the same time, roughly 21,000 soldiers from the Fourth Red Army attacked Gansu, wanting to find a way to the Soviet Union . By the end of 1936, they were defeated by the Nationalist forces' General Ma Bufang , with more than 6,000 soldiers being captured. Only Xu Xiangqian and other senior officers survived. Because of this great failure,

245-474: A total of 20,000 soldiers and planned to occupy Guangzhou . However, they were defeated before they reached Guangzhou with only a few thousand men surviving the battle. Zhu De led a column of survivors to Hunan to fight in the Autumn Harvest Uprising where they were defeated again.

294-550: Is not an entity for fighting only. Its major task (or function) is to mobilize the masses. Fighting is only a means." This process involved the Red Army's significant responsibility for educating, organizing, and mobilizing the masses, functioning like the mobile embodiment of the Communist Party in addition to its military roles. Academic Cai Xiang writes that the Red Army's ability to function in this way helps explain why despite

343-912: The Chinese Red Army during the encirclement campaigns of the Chinese Civil War and later against the Imperial Japanese forces during the early years of the War of Resistance-World War II . O-2Ms (sometimes mislabeled as Douglas O-38 s ) were heavily deployed in the Battle of Shanghai , the Battle of Nanjing , and the Battle of Taiyuan . As their slow speed made the O-2Ms vulnerable to fast Japanese fighters, they either flew clandestine night missions solo or day missions escorted by Hawk IIs or Hawk IIIs . Japanese ace fighter pilot Akio Matsuba , flying an A2N from

392-831: The Chinese Workers' and Peasants' Red Army or just the Red Army , was the military wing of the Chinese Communist Party from 1928 to 1937.

Also in the summer of 1928, Peng Dehuai , the Nationalist forces Regimental Commander, led a military mutiny. A Nanchang uprising survivor, He Long, also created an army in his hometown, with former government soldiers as the main fighting force. In the late 1920s, the Communist forces lacked resources and relied on guerilla tactics such as hit-and-run operations to compensate for their material limitations. In early 1930, more red armies were created and

637-517: The Fourth Red Army in autumn. In 1934, the Nationalist forces purchased new German weapons and launched a fifth large-scale attack on the Red Army's base area in Jiangxi. The First Red Army lost more than 50,000 soldiers in this battle and had to leave Jiangxi to establish a new base. This was the beginning of the Long March . About 30,000 soldiers were left to defend the base areas in southern China. During

686-668: The Fourth Red Army's Commander in Chief Zhang Guotao was stripped of his military power. When the anti-Japanese war broke out on 7 July 1937, the communist military forces were nominally integrated into the National Revolutionary Army of the Republic of China , forming the Eighth Route Army and the New Fourth Army units. The First Red Army was integrated into the 115th Division of the Nationalist forces. The Second Red Army

Several of the Nationalist forces' generals were also captured. In 1933, the Fourth Red Army arrived at Sichuan and recruited more than 80,000 soldiers. This caused Sichuan's warlord Liu Xiang to gather 200,000 troops to attack

784-435: The Nationalist forces' future generals participated in this battle such as Huang Wei , Du Yuming , Sun Li-jen , and others.

833-506: The Nationalist forces. The Chinese Red Army made use of artillery seized from the enemy forces. Most of the time the Red Armies only had mortars, with typically every army having three to five mortars. During the summer of 1930, Peng Dehuai 's Fifth Army captured four 75mm mountain guns in Yuezhou, but they lacked the required ammunition. In the spring of 1931, the Fourth Red Army captured

882-540: The Party and the military was further institutionalized by the establishment of the Central Military Commission . In the view of the Communist Party, participation of the masses in the Red Army was significant beyond the direct concerns of manpower and material support. It was also viewed as a political process through which the masses would evolve into "masters of the state." According to Mao, "[T]he Red Army

931-407: The Red Army recruited red guards. The red guards were commanded by officers of the local soviet . When large-scale war broke out, the red guards were responsible for the logistical support of the Red Army and supplied new soldiers for the Red Army. For example, in the winter of 1932, Xiao Ke 's Eighth Army had 2,200 red soldiers and 10,000 red guards. The red guards' officers were not always loyal. In

980-559: The US Army, plus one civil O-2BS modified specially for James McKee , who made a remarkable trans-Canada flight in September 1926. In 1927, the O-2BS was adapted as a three-seater with a radial engine. The O-2Hs were an entirely new design but continued the same basic model number. Major differences were heavily staggered wings, a more compact engine installation, and clean landing gear secured to

Similar movements also occurred in western Hubei; in the spring of 1931, Xia Xi took over He Long's army and killed most of his senior officers including Duan Dechang . In the fall of 1932, the Nationalist forces gathered 300,000 soldiers to attack the Fourth Red Army. Most of

1127-460: The article The Democratic Movement within the Army , written during the Second Sino-Japanese War , Mao Zedong discussed the Red Army's political work and stated, "Through the democratic movement under centralized leadership, we were able to achieve a high degree of political unity, improve lives, and improve military technology and tactics, which are our three main purposes." This view of democracy in

In 1931, the Chinese Red Army defeated the Nationalist forces three times with a large-scale attack, causing the Nationalist forces to lose nearly 100,000 soldiers. Several smaller red armies came together and formed a group army. In the summer of 1931, General Zhang Guotao arrived at the Fourth Red Army's base area and took over

1225-478: The first of which was powered by the 420 hp (313 kW) Liberty V-1650-1 V-engine and test-flown in the autumn of 1924. The second XO-2 was powered by the 510 hp (380 kW) Packard 1A-1500 Vee engine, which proved unreliable. The US Army ordered 45 O-2 production aircraft in 1925, which retained the XO-2's welded steel tube fuselage, wooden wings, and overall fabric covering. It introduced aluminum panels on

1274-597: The first years of the war. The largest rebellion was the Ningdu Uprising which occurred in the winter of 1931. General Dong Zhentang  [ zh ] , head of the 26th Route Army of the National Revolutionary Army and his 17,000 soldiers were the first to join the First Red Army. After the uprising, the Nationalist Party strengthened its control over the army, making launching a military rebellion more difficult. Despite this, General Zhang Guotao , who regarded

1323-411: The former officers of the Nationalist forces with disdain, lead an attack in the summer of 1931 which killed more than 2,500 of the Fourth Red Army's middle and senior officers who originated from the Nationalist forces. The Chinese Red Army had no ranks. Officers and soldiers were considered equal. Early on, the officers were elected by the soldiers; however, during the later parts of the war this system

1372-554: The forward fuselage. The XO-2 had been flown with short and long-span wings, the latter giving improved handling and therefore being specified for the production aircraft. The fixed tailskid landing gear included a main unit of the divided type, the horizontal tail surface was strut-braced, and the engine was cooled by a tunnel radiator . The O-2 proved to be a conventional but very reliable biplane , which soon attracted orders for 25 more aircraft: 18 O-2A machines equipped for night flying and six O-2B dual-control command aircraft for

1421-449: The fuselage. Douglas produced 879 of all variants, with 770 going to the U.S. military. Up to 2011, no O-2s had been known to exist. However, in 2011, the wreckage of O-2H 29-163 that crashed out of Kelly Field, Texas, on March 16, 1933 has been positively identified. The rear and central/forward portion of the fuselage behind the firewall, wing attachments and landing gear parts, tailplane, and many engine parts, as well as eight of

1470-509: The impact. His body was recovered, but the wreckage was abandoned due to the airframe and engine both being a write-off. There is an M-2 on display at the Udvar-Hazy museum ; the aircraft was used as a mail plane in the late 1920s before it crashed in January 1930, eventually being used as display aircraft since 1940. The only similar aircraft known to exist is a restored Douglas M-2 mailplane and

1519-461: The local forces lacked rifles. In the summer of 1934, Xun Huaizhou  [ zh ] 's Seventh Legion had 6,000 soldiers but only 1,200 rifles, which lead to the Seventh Legion's quick defeat when they attempted to attack Fuzhou . Every Red Army regiment typically had one machine gun company, with every company having six or more machine guns. The machine gun equipment rate of the Red Army

1666-437: The new officers who were formerly farmers. Each base area established its own military academies, usually using captured enemy officers as teachers. The enterprise was very successful, and by 1936 most of the Red Army's military officers were former farmers. In 1931, commanders determined that there were a number of spies in the Red Army. This issue became particularly prevalent when the First Red Army's Chief of Staff Zhu Yunqing

1715-408: The number of red soldiers grew rapidly. By the summer of 1930, the Chinese Red Army had grown to more than 100,000 soldiers and had several base areas, such as in southern and northern Jiangxi, western Hubei , and eastern Hunan, among others. Peng Dehuai's Fifth Army attacked and occupied Changsha , the capital of Hunan. After the attack, Jiangxi became the largest base area of the Chinese Red Army. In

1764-467: The other two. In 1930, the Chinese Red Army had established several base areas. Though the designations of the Red Army changed frequently, the main leadership of base areas did not change significantly. In the early phases of its establishment, most of the Chinese Red Army's military officers were made up of former officers of the Nationalist forces, with most of them joining the Red Army secretly between 1925 and 1928. Many of these officers were killed in

1813-569: The same time, the Fourth Red Army defeated Liu Xiang 's attacks, who lost more than 80,000 soldiers in battle. Before the First Red Army began the Long March, Xiao Ke 's Sixth Legion arrived at eastern Guizhou and joined forces with He Long 's Third Army. After this, the Third Army changed its designation to Second Legion. In the autumn of 1935, the First Red Army arrived in northern Shaanxi with only 6,000 soldiers after losing more than 80,000 along

1862-448: The soldiers from the Red Army's militia troops were armed with cold weapons at all times. In the autumn of 1930, Zeng Zhongsheng commanded 30,000 red guards who were armed with cold weapons. Despite the overwhelming numbers of red soldiers, 1,000 opposing troops armed with rifles were able to defeat Zeng Zhongsheng's forces. The Chinese Red Army used various types of submachine guns from Thompsons to MP 18s . They were captured from

1911-516: The spring of 1933, one of the red guards' officers killed 29th Army's commander Chen Qianlun and surrendered to the Nationalist forces. Usually each Chinese Red Army's army or legion had three or two infantry divisions. Each division has three infantry regiments and one mortar company. In different time the number of one division's soldiers is different. In the beginning every division had about 1000 or 2000 men. From 1933 to 1936, one division usually had about 5000 or 6000 men. After several uprisings,

Rogers on a night recon advanced training mission. Apparently flying low, the aircraft hit a hill and burned after the crash, leaving only the found wreckage today. Weather was not considered a contributing factor. Cadet Rogers was instantly killed in the crash by

2009-525: The war, including through mass mobilization campaigns operating behind enemy lines. At the end of the Second Sino-Japanese War, the Red Army had 2 million militia members and 900,000 regular troops. In 1947, the Red Army was reorganized into the People's Liberation Army. It continued to operate as a guerilla army reliant on the support of the peasantry. By the time the People's Republic of China

2058-581: The way. During this same time, the Fourth Red Army moved to northern Sichuan and planned to attack Chengdu . By the end of 1935, they had lost more than 40,000 soldiers and were defeated. Therefore, they were forced to move to southern Gansu and wait for He Long 's Second Legion and Sixth Legion to arrive. In the summer of 1936, the Second Legion, the Sixth Legion and the Thirty-Second Army formed

It was developed into several versions, with 879 being produced in total. It was used in combat by the Chinese Air Force in the 1930s and also was the basis for a successful mailplane version. The important family of Douglas observation aircraft sprang from two XO-2 prototypes,

2205-408: Was assassinated by a spy in a hospital. After this, each Red Army began to judge and execute the officers and soldiers who were suspected. In 1931, the First Red Army executed about 4,000 men. The Fourth Red Army and Third Red Army also executed thousands of officers, especially senior officers. Typically a Red Army's base area was surrounded by enemy forces. To protect the base area from enemy attack,

2254-403: Was eliminated. From regiment to army, the command system at each level had four commanders: commander, political commissar, chief of staff, and director of political department, with the political commissar holding the most power.

After the Communist Party assumed power in 1949, veterans of the Red Army were venerated in mainland Chinese culture and are distinguished from those who joined to fight with the Communist Party after the integration with the Nationalists, or during the second civil war. In 1954, the relationship between

2352-492: Was integrated into the 120th Division of the Nationalist forces. The Fourth Red Army was integrated into the 129th Division of the Nationalist forces. These three divisions had 45,000 soldiers in all. 10,000 soldiers were left to defend the base areas in northern Shaanxi . In southern China, the New Fourth Army 's 10,000 soldiers acted as a guerrilla force. At the time of the Second Sino-Japanese War , these two armies contained one million armed men. The Red Army grew rapidly during

2401-523: Was no less than that of the Nationalist forces' elite troops. This was one of the important reasons why the Red Army was able to defeat the Nationalist forces on many occasions. The most common machine guns were the MG08 , ZB vz. 26 , M1918 Browning Automatic Rifle , and Hotchkiss M1914 machine gun . Due to the lack of rifles, the Chinese Red Army was forced to use cold weapons such as broadswords, spears, sabres, and other melee implements. In particular, most of
