So, in a war that's rather forgotten due to the much larger conflicts both before and after it, Poland and the newborn Soviet Union went to war in 1919, the Polish-Soviet War. The reasons for the war are complex, being a combination of a desire amongst the Polish to regain the eastern territories that were lost in the various partitions and to liberate the Ukraine, whilst the Soviets generally viewed the conflict as the first step of exporting communism to central Europe and beyond, though that's a bit of a simplification
Anyway, things went well for the Polish at first, taking Minsk on the 8th of August and later Kiev on the 7th of May 1920, only to be driven out again on the 13th of June that year after which things started to take a turn for the worst...only to culminate with the Battle of Warsaw where the Polish took a hundred thousand Soviet troops off the board in a battle so great as to be called the Miracle of Vistula thanks to the breaking of Soviet ciphers, entire divisions just falling apart as the Polish launched a counter attack leading to battles like the Battle of Komarów where Polish cavalry killed nearly ten times their own losses, then the Battle of the Niemen River, another major Polish victory followed by a continued advance on all fronts, after which the exhausted Soviets sued for peace.
That would become the Peace of Riga, which put the borders of Eastern Europe like this:
But just how bad could the war have gone for the Soviets in the worst case scenario? I'll admit I've got little more knowledge about the topic than what the Wikipedia page can give me, so its a mile wide and an inch deep and meaning that this thread is as much a chance for me to learn as it is a question, but there seems to be a number of avenues for things to get much worse.
According to the Wiki, the British were starting to get involved...
...alongside France and other powers.
Could Poland have done even better - or the USSR done even worse - if such supplies and troops were allowed through? And what might the aftermath of a better performing Poland be? According to the Wiki (a questionable source at best, I know, but the best one I've got right now ) one of the Polish plans was to create an Intermarium Federation led by Poland that would comprise "Poland, Lithuania, Ukraine, and other Central and East European countries emerging out of crumbling empires after the First World War" in order to serve as a counterweight against Germany and Russia, but could this actually be created even in a timeline where Poland performs at its best and the USSR at its worst?
All info is welcome!

According to the Wiki, the British were starting to get involved...
Britain's Prime Minister, David Lloyd George pressed Poland to make peace on Soviet terms and refused any assistance to Poland that would alienate the Whites in the Russian Civil War. In July 1920, Britain announced it would send huge quantities of World War I surplus military supplies to Poland, but a threatened general strike by the Trades Union Congress, who objected to British support of "White Poland", ensured that none of the weapons destined for Poland left British ports. David Lloyd George had never been enthusiastic about supporting the Poles, and had been pressured by his more right-wing Cabinet members such as Lord Curzon and Winston Churchill into offering the supplies.
On 11 July 1920, the government of Great Britain sent a telegram to the Soviets, signed by Curzon, which has been described as a de facto ultimatum. It requested that the Soviets halt their offensive at the Curzon line and accept it as a temporary border with Poland, until a permanent border could be established in negotiations. In case of Soviet refusal, the British threatened to assist Poland with all the means available, which, in reality, were limited by the internal political situation in the United Kingdom. On 17 July, the Bolsheviks refused and made a counter-offer to negotiate a peace treaty directly with Poland. The British responded by threatening to cut off the ongoing trade negotiations if the Soviets conducted further offensives against Poland. These threats were ignored.
...alongside France and other powers.
France, continuing its policy of countering Bolshevism now that the Whites in Russia proper had been almost completely defeated, sent a 400-strong advisory group to Poland's aid in 1919. It consisted mostly of French officers, although it also included a few British advisers led by Lieutenant General Sir Adrian Carton De Wiart. The French officers included a future President of France, Charles de Gaulle; during the war he won Poland's highest military decoration, the Virtuti Militari. In addition to the Allied advisors, France also facilitated the transit to Poland from France of the "Blue Army" in 1919: troops mostly of Polish origin, plus some international volunteers, formerly under French command in World War I. The army was commanded by the Polish general, Józef Haller. Hungary offered to send a 30,000 cavalry corps to Poland's aid, but the Czechoslovakian government refused to allow them through, as there was a demilitarized zone on the borders after the Czechoslovak-Hungarian war that had ended only a few months before. Some trains with weapon supplies from Hungary did, however, arrive in Poland.
