 (...) The Czechs put together a substantial body of infantry - about 15,000 men - and on 23 January 1919, they invaded the Polish-held areas. To confuse the Poles, the Czechs recruited some Allied officers of Czech background and put these men in their respective wartime uniforms at the head of the invasion forces. After a little skirmishing, the tiny Polish defense force was nearly driven out." Watt fails to mention the Czech opposition to Sejm elections as well as prior deployment of Polish troops and arming up of Poles in the disputed area.

In 1919, the matter went to consideration in Paris before the World War I Allies. Watt claims the Poles based their claims on ethnographical reasons and the Czechs based their need on the Teschen coal, useful in order to influence the actions of Austria

Watt overlooks the Czech minority in the region, as well as the urgent Czechoslovak need for the only railway running to war-torn eastern Slovakia which passed through Zaolzie. The Allies finally decided that the Czechs should get 60 percent of the coal fields and the Poles were to get most of the people and the strategic rail line. Watt writes: "Czech envoy Edvard Beneš

As it turned out, Beneš knew what he was doing. A plebiscite would take some time to set up, and a lot could happen in that time – particularly when a nation's affairs were conducted as cleverly as were Czechoslovakia's."

Watt argues that Beneš strategically waited for Poland's moment of weakness, and moved in during the Polish-Soviet War

As Watt writes, "Over the dinner table, Beneš convinced the British and French that the plebiscite should not be held and that the Allies should simply impose their own decision in the Teschen matter. More than that, Beneš persuaded the French and the British to draw a frontier line that gave Czechoslovakia most of the territory of Teschen, the vital railroad and all the important coal fields. With this frontier, 139,000 Poles were to be left in Czech territory, whereas only 2,000 Czechs were left on the Polish side".

"The next morning Beneš visited the Polish delegation at Spa. By giving the impression that the Czechs would accept a settlement favorable to the Poles without a plebiscite, Beneš got the Poles to sign an agreement that Poland would abide by any Allied decision regarding Teschen. The Poles, of course, had no way of knowing that Beneš had already persuaded the Allies to make a decision on Teschen. After a brief interval, to make it appear that due deliberation had taken place, the Allied Council of Ambassadors in Paris imposed its 'decision'.

Part of Czechoslovakia (1920-1938)

The local Polish population felt that Warsaw had betrayed them and they were not satisfied with the division of Cieszyn Silesia. About 12,000 to 14,000 Poles were forced to leave to Poland. It is not quite clear how many Poles were in Zaolzie in Czechoslovakia. Estimates (depending mainly whether the Silesians

 numbers are not accurate since nationality depended on self-declaration and many Poles filled in Czech nationality mainly as a result of fear of the new authorities and as compensation for some benefits. Czechoslovak law guaranteed rights for national minorities but reality in Zaolzie was quite different. Local Czech authorities made it more difficult for local Poles to obtain citizenship, while the process was expedited when the applicant pledged to declare Czech nationality and send his children to a Czech school. Newly built Czech schools were often better supported and equipped, thus inducing some Poles to send their children there. Czechs schools were built in ethnically almost entirely Polish municipalities. This and other factors contributed to the cultural assimilation

 typical for the years around 1920 receded and local Poles increasingly co-operated with Czechs. Still, Czechization was supported by Prague, which did not follow certain laws related to language, legislative and organizational issues. Polish deputies in Czechoslovak National Assembly frequently tried to put that issues on agenda. One way or the other, increasingly local Poles thus assimilated into the Czech population.

It 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 this outcome, and were happy to give up the sacrifice of a small provincial rail centre to Poland in exchange for the ensuing propaganda benefits.

. The vast majority of the local Polish population enthusiastically welcomed the change, seeing it as a liberation and a form of historical justice, but they quickly changed their mood. The new Polish authorities appointed people from Poland to various key positions from which locals were fired. The Polish language became the sole official language. Using Czech (or German) by Czechs (or Germans) in public was prohibited and Czechs and Germans were being forced to leave the annexed area or become subject to Polonization

) by choice or forcibly. The behaviour of the new Polish authorities was different but similar in nature to that of the Czechoslovak ones before 1938. Two political factions appeared: socialists (the opposition) and rightists (loyal to the new Polish national authorities). Leftist politicians and sympathizers were discriminated against and often fired from work. The Polish political system was artificially implemented in Zaolzie. The local Poles continued to feel like second-class citizens and a majority of them were dissatisfied with the situation after October 1938. Zaolzie remained a part of Poland for only 11 months until the invasion of Poland started on September 1, 1939.

Richard M. Watt describes the Polish capture of Teschen in these words: "Amid the general euphoria in Poland – the acquisition of Teschen was a very popular development – no one paid attention to the bitter comment of the Czechoslovak general who handed the region over to the incoming Poles. He predicted that it would not be long before the Poles would themselves be handing Teschen over to the Germans."

Watt also writes that "the Polish 1938 ultimatum to Czechoslovakia and its acquisition of Teschen were gross tactical errors. Whatever justice there might have been to the Polish claim upon Teschen, its seizure in 1938 was an enormous mistake in terms of the damage done to Poland's reputation among the democratic powers of the world."
