The exhibition marks the 80th anniversary of the establishment of a training base for the Polish Special Operations Executive (SOE) during the war.
Audley End, a grand 17th-century mansion, was then called Station 43. It is now under the care of the English Heritage charity.
The charity recently identified the names of six Polish special forces trainees scrawled on the wall of a candle store in the house’s coal gallery.
The exhibition features the stories of these men, along with other artefacts and accounts from the time.
On display are also devices used in secret communications training, everyday objects adapted to conceal and carry hidden messages, and a selection of photographs.
In a statement for the media, English Heritage historian Andrew Hann said that the story of the Silent and Unseen unit, also known as the Cichociemni, at Audley End House "has long been a source of fascination, and we’re delighted to have been able to identify the men whose names have been scrawled onto the wall of the house’s Coal Gallery candle store."
He added: "Their story is of particular pertinence, given current events in Ukraine. With ever changing land boundaries, there is a deep connection between the Ukrainian and Polish people. Indeed, one of the men who scratched his name onto the wall at Audley End came from Lviv, and another studied at university there.”
Some 2,500 volunteered for service in the Silent and Unseen unit, with around 700 finally completing the course.
In total, 316 were parachuted into Poland to join underground resistance. Of this number, 112 were killed, nine during flights or jumps, and 84 in combat or murdered by Germany's Gestapo secret police. Ten took poison after being arrested and nine were executed after the war in the wake of mock trials in Stalinist courts.
The exhibition at Audley End House runs until October 31.
