The two men served in different companies of the same regiment. Their companies launched a joint attack on one entrance of the Gibraltar tunnel complex. Despite fierce resistance by the British, the mission was accomplished.
It is not possible to discover at this time the nature of BLUCHER’S mission. Will continue inquiries, but would be glad to learn whatever you discover on your end.
You will recall the circumstances of BLUCHER’s relief in Latvia and subsequent court-martial. Also, Governor Bach’s role. Urge you not let past history or personal animus interfere with relations.

 This part of eastern Germany was transferred to Poland after the Great War. Germans who remained in the “Polish corridor” after the territory transfer felt themselves to be a persecuted minority.
