Our airmen had hardly reconciled to the fate of their homeland and were looking for ways to fight the Nazi Third Reich abroad after the establishment of the Protectorate of Bohemia and Moravia. When the United Kingdom found itself under attack, the Czechoslovaks fought for help and quickly joined the RAF. The traditional sets of four silver coins of the Czech Mint remind us of the important events that our flying heroes have written in history in 2018.

The relief depicts the first deployment of the 310th Fighter Squadron in the Battle of Britain, the KX-B emergency landing in the North Sea, Operation Stonewall, and the triumphant return of Czechoslovaks to their homeland.

What's under the code name "Stonewall"? Five ships , whose task was to break the British naval blockade and strengthen the German war machine, sailed from Japan in 1943. It was not about battleships, but about cargo ships that carried vital commodities in the crucial year of the war. They sailed fast and lonely in order to escape the enemy's attention. Yet they were armed for all cases. They were called "blockade breakers". Alsterufer, which had 344 tons of tungsten for the Hitler armor, was the most important of these. It escaped when the British patrol aircraft saw it in the North Atlantic, and the German Air Force and Navy came to help. The British wanted the ship to sink at any cost, so the race with time started. Eight Czechoslovaks, who are crew members of the Liberator bomber 311 brigade, were also involved in the hunt. Inspite of danger of the furious Alsterufer gunfire, they made a headfirst air strike and repeatedly hit it. The ship sank with the precious cargo, which represented the year-round consumption of the imperial warfare economy! No wonder our airmen soon became celebrities. The British newspaper, the Parliament and even King George VI appreciated them. Even the captain of the sunken vessel eventually recognized their cold-blooded power.

On the reverse side of the coins made by an academic sculptor Zbynek Fojtu there are war scenes, when the Czechoslovak fighters attack a German bomber above Ottoman cliffs; the Wellington bomber crew is released to grace for elements and hostile captivity after an emergency landing; the bomber Liberator sinks the blockade breaker; Prague welcomes its airmen returning from exile. The common obverse side belongs to the attributes of the Niue Island, which is a foreign issuer that allows the Czech Mint to issue its own commemorative coins. These are the name and the portrait of Queen Elizabeth II, the year of the issue 2018 and the nominal value of 1 DOLLAR (NZD). These attributes are surrounded including years of events depicted on individual coins.

An attractive wooden etui decorated with thematic engraving conceals apart from four silver mintages also a booklet with treatise of PhDr. Lubor Vaclavu, who is military historian and project adviser.
