维基百科英语版词条“Polish–Czechoslovak border conflicts”（https://en.m.wikipedia.org/wiki/Polish%E2%80%93Czechoslovak_border_conflicts）记载：
Within the region originally demanded from Czechoslovakia by Nazi Germany in 1938 was an important railway junction city of Bohumín. The Poles regarded the city as of crucial importance to the area and to Polish interests. On 28 September, Beneš composed a note to the Polish administration offering to reopen the debate surrounding the territorial demarcation in Těšínsko in the interest of mutual relations, but he delayed in sending it in hopes of good news from London and Paris, which failed to come. Beneš then turned to the Soviet leadership in Moscow, which had begun a partial mobilisation in eastern Belarus and Ukraine and threatened Poland with the dissolution of the Soviet-Polish non-aggression pact. At noon on 30 September, Poland gave an ultimatum to the Czechoslovak government that demanded the immediate evacuation of Czechoslovak troops and police and gave Prague time until noon the following day. At 11:45 a.m. on 1 October the Czechoslovak foreign ministry called the Polish ambassador in Prague and told him that Poland could have what it wanted. The Polish Army, commanded by General Władysław Bortnowski, annexed an area of 801.5 km2 with a population of 227,399 people. The Germans were delighted with the outcome. They were happy to give up a provincial rail centre to Poland. It was indeed a small sacrifice, spread the blame of the partition of Czechoslovakia, made Poland an accomplice in the process and confused the issue as well as political expectations. Poland was accused of being an accomplice of Nazi Germany. In November 1938, Poland crossed into Slovakia where a minor firefight took place at Spisz, resulting in two fatalities on the Polish side, before the Slovak withdrawal. Poland occupied some northern parts of Slovakia and received from Czechoslovakia Zaolzie, territories around Suchá Hora and Hladovka, around Javorina, and in addition the territory around Lesnica in the Pieniny Mountains, a small territory around Skalité and some other very small border regions. Poland officially received the territories on 1 November 1938 (see also Munich Agreement and First Vienna Award).
