On 12 August the Multinational Corps Northeast celebrated the Polish Armed Forces Day.
It is a national holiday celebrated annually on 15 August in Poland, commemorating the anniversary of a decisive Polish victory over Soviet Russia at the Battle of Warsaw in 1920, during the Polish-Soviet War.
In the event known as the 'Miracle on the Vistula', the Polish Armed Forces successfully repelled the Red Army's offensive outside Warsaw in August 1920. The defeat of the Soviet forces saved the capital and ensured the survival of the young Second Polish Republic.
The Soldier's Day was proclaimed in 1923 and the date of 15 August was chosen to commemorate the decisive moment of the Battle.
