The Eastern Legion When the Great War broke out it was a sign to mobilize Polish patriotic paramilitary organizations. On 27 August 1914,
Józef Piłsudski issued an order in which he declared formation of the
Polish Legions. On the strength of the order the Eastern Legion was formed in Lviv under the command of the General Adam Pietraszkiewicz. Haller was one of the founders of this formation which is a combination of Falcon's Drużyny Polowe (Fields Brigades), and the Polskie Drużyny Strzeleckie (
Polish Rifle Squads). At that time Austrian failures in
Galicia led to occupation of
Lviv and the whole territory of the eastern Galicia by the
Russian army. The Legion had to withdraw into the surroundings of
Mszana Dolna. Although the unit had been completely formed it did not participate in the battle. Due to a collapse of morale among soldiers and resistance against swearing loyalty to the
Austrian emperor, the legion was disbanded.
Polish Legions Soldiers, who were in favor for continuing the war against the
Russian Empire, were subjected to Joseph Haller's directions. He became the commander of the
3rd Legions' Infantry Regiment after its former reorganisation. He was then ranked lieutenant-colonel. On 30 September 1914, Haller and the military unit under his surveillance left
Kraków, and set off to the front line in
Eastern Carpathians. Despite bad climatic and topographic conditions, the brigade supported the defence of the Carpathians and hindered Russian access to Hungary. In the beginning of October 1914, the brigade got to Hungarian side of Carpathians. On October 12 the 3rd Legions' Infantry Regiment troops under the command of Haller surmounted the
Rafajlowa village in
Galicia. On 22 and 23 October the main troops reached the village through the route near the
Pantyr Mountain in
Gorgany (later on it was named the Legions’ Mountain Pass), built by sappers and assaulted on
Stanisławów. On 24 October the troops defeated
Nadvirna. Five days later the Molotkow battle took place. The failure pushed Haller's soldiers back to Rafajlowa. In November the brigade was divided into two separate units. Haller's brigade remained in Rafajlowa, whereas the others continued the battle in Huculszczyzna and Bukovina. On the night of 24 January 1915, Russians attacked the 3rd Legions' Infantry Regiment. Polish soldiers did not expect the offensive. However, due to their commander's actions, they defeated the enemy and took many
Prisoners of War (POWs). A permanent struggle resulted in the loss of approximately 50% of soldiers. After the successful defence and stabilization on the front line, lieutenant colonel Haller passed the leadership of the 3rd Legions' Infantry Regiment to major
Henryk Minkiewicz, simultaneously remaining in the 2nd Legions’ Infantry Brigade as commander's orderly officer. On 14 March 1915 he was promoted colonel. On a temporary permit in
Częstochowa, in May 1915 Haller was injured in a car accident. He spent 10 months recovering in a hospital. In spring of 1916 Haller became a member of the Colonels’ Council, which incorporated the heads of Legions’ military units, and functioned in opposition to Legions’ Headquarters, which advocated Austrian policy. In July 1918 Haller was given an assignment to command the 2nd Legions’ Infantry Brigade, which he accepted.
Polish Rifle Division On 15 February 1918, Haller questioned the agreements of the
Treaty of Brest-Litovsk which reduced the chances for the creation of an independent Poland,. Together with the
II Brigade of the Polish Legions and the rest of Polish soldiers, Haller
broke through the frontline near Rarańcza. and joined the Polish troops in Russia. He was ranked commander of a newly formed
Polish 5th Siberian Rifle Division. From 28 March 1918, he took charge of the military units of the
Polish 2nd Corps in Ukraine. On 7 April 1918 Haller was appointed
General. The legions under Haller's command were inspired by the
National Democracy movement. Recruitment of Jewish volunteers to their ranks ceased in 1918, and the legions were later involved in pogroms.
Kaniów Germany considered the presence of Polish military units in Ukraine an infringement of the
Treaty of Brest-Litovsk. At midnight on 10–11 May 1918 German troops assaulted Polish units near
Kaniv (Polish: Kaniów). There were no warnings preceding the attack. The battle continued for one day. After the ammunition storage expired, the Polish 2nd Corps surrendered. Many people were seriously injured. The Polish army lost less than 1000. the Germans close to 1500. Haller avoided imprisonment by faking his own death. Using the name "Mazowiecki" he fled to Moscow, where he became the head of Polish Army Commission.
France battle flag. In July 1918, after a long journey through
East Karelia and
Kola Peninsula to
Murmansk, General Haller arrived in France. On 4 October 1918 he was designated to be in charge of the forming Polish Army. Those units were organised by volunteers. They consisted of Polish men who firstly served in the French army, former POWs of Austrian-Hungarian and German armies (nearly 35,000) and Polish emigrants from the United States and Canada (about 23,000 people) and
Brazil (300 people). Political surveillance over the army was initially a domain of
Polish National Committee. But according to an agreement of 28 September 1918, the
Blue Army was recognised by the
Triple Entente member countries and the independent Polish army. In 1918 Polish troops commanded by Joseph Haller struggled with German soldiers on the western front line in the Vosges mountain region and
Champagne.
Blue Army The end of war did not interrupt the enlargement of the Polish army in France, also known as the
Blue Army due to their uniforms. The number of soldiers was eventually over 100,000. Due to weapons supplied from France, the Polish Army finally became a significant military force. Beginning in April 1919, men and equipment were conveyed to Poland. Modern arms of the Blue Army, especially airplanes and
Renault FT tanks enhanced the
Polish Armed Forces yet to be founded. General Haller arrived in Warsaw on 21 April 1919, where he was welcomed as a national hero. He was granted honorary citizenship of Warsaw. The Blue Army was involved in anti-Jewish violence and its soldiers participated in pogroms. ==World War I aftermath==
