Nearly Captured
Capt. Czech, her name while in Europe, was nearly captured when she was coming back into Warsaw.
The Washington Post:
"Capt. Czech, as she was then known, traveled often unaccompanied far from Warsaw under the pretense of seeking news of family members in the aftermath of the war. Sometimes those relatives surfaced, and during extended stays with them, she was credited in official documents with reporting back 'considerable' intelligence on Soviet troop movements, the activities of the Soviet and Polish security forces, and economic and political data that could not otherwise be obtained by American embassy officials.
She was also put to work as a courier between Berlin and Warsaw and was almost captured when returning to Warsaw on Jan. 15, 1946, with top-secret documents intended for embassy personnel. As she approached the German-Polish border checkpoint on foot, she gingerly slipped the package of materials to a less suspicious traveler and instructed the person to take the files to a safe address in Warsaw."
