There were armed clashes and fatalities in some villages over the following two years. Slovaks from the Polish part of Spiš settled mainly in the newly created industrial town of Svit near Poprad, Kežmarok, Poprad, and in depopulated German villages  near Kežmarok. Slovaks from the Polish part of Orava settled mainly in Czech Silesia, and in depopulated German villages in the Czech lands . On 10 March 1947 a treaty guaranteeing basic rights for Slovaks in Poland was signed between Czechoslovakia and Poland. As a result, 41 Slovak basic schools and 1 high school were opened in Poland. Most of these however were shut down in the early sixties because of lack of Slovakian teachers. On June 13, 1958, in Warsaw, the two countries signed a treaty confirming the border at the line of January 1, 1938 , and since then there have been no conflicts regarding this matter. In March 1975 Czechoslovakia and Poland modified their border along the Dunajec to permit Poland to construct a dam in the Czorsztyn region, southeast of Kraków.

Q: Passage: The situation became more complicated with the landing in Murmansk of 130 British Royal Marine Light Infantry on 6 March to prevent the Germans  from gaining the White Sea coast and the Murmansk Railroad. By June 1918, an assortment of British Royal Marines, French artillerymen, part of a Serb battalion, Poles, Red Russians from the Murmansk Soviet, and some Red Finns occupied the railway line from Murmansk south as far as Kem. The arrival of British reinforcements and an Allied plan for them to link up with anti-Bolshevik units in Siberia prompted Trotsky, now at peace with the Germans, to send 3,000 Red troops northwards. In July these troops were disarmed and seen off by the British, who advanced as far south as Sorokka.  British-led forces defending the railway line included a battalion of 1,400 Red Finns and the Karelian regiment also known as the "Irish Karelians" after Colonel P.J. Woods of the Royal Irish Rifles who raised and led the regiment formed of the local Karelians. The situation of the Viena expedition began to deteriorate. The Karelian regiment stationed in Kem attacked the Finnish troops at Jyskyjärvi on 27 August. 18 men were lost. The next attack came against Luusalmi on 8 September when 42 Finns were killed.  Subsequent battles were fought at Kostamus and Vuokkiniemi in September-October. The Finnish troops withdrew to Finland on 2 October.  Of these troops, 195 survived and made their way home; 83 were killed. The British forces withdrew in October 1919 and the situation of the Russian White Army collapsed.

Q: Passage: Although the Curonians had attacked Riga in 1201 and 1210, Albert of Buxhoeveden, considering Courland a tributary of Valdemar II of Denmark, had been reluctant to conduct a large scale campaign against them. After Albert's death in 1229, the crusaders secured the peaceful submission of Vanemane  by treaty in 1230. In the same year the papal vice-legat Baldouin of Alnea annulled this agreement and concluded an agreement with the ruler of Bandava in the central Courland Lamekins , delivering his kingdom into the hands of the papacy. Baldouin became the popes's delegate in Courland and bishop of Semigallia; however, the Germans complained about him to the Roman Curia, and in 1234 Pope Gregory IX removed Baldouin as his delegate. After their decisive defeat in the Battle of Saule by the Samogitians and Semigallians, the remnants of the Swordbrothers were reorganized in 1237 as a subdivision of the Teutonic Order, and became known as the Livonian Order. In 1242, under the leadership of the master of the Livonian Order Andrew of Groningen, the crusaders began the military conquest of Courland. They defeated the Curonians as far south as Embūte, near the contemporary border with Lithuania, and founded their main fortress at Kuldīga. In 1245 Pope Innocent IV allotted two thirds of conquered Courland to the Livonian Order, and one third to the Bishopric of Courland. At the Battle of Durbe in 1260 a force of Samogitians and Curonians overpowered the united forces of the Livonian and Teutonic Orders; over the following years, however, the Crusaders gradually subjugated the Curonians, and in 1267 concluded the peace treaty stipulating the obligations and the rights of their defeated rivals. The unconquered southern parts of their territories  were united under the rule of the Grand Duchy of Lithuania.
Question: When did the Curonians first attack?
