One of Churchill's acts as prime Minister was to lock up all "enemy aliens" out of fear of fifth columnists. However, over time men of military age were permitted to join the Pioneer Corps in unarmed roles and eventually volunteer to serve in combat arms.
Some escaped internment. Klaus Hugo Adam, born in 1921 to an assimilated German Jewish family in Berlin, (owers of the sport store S Adam) joined the RAF and flew Typhoon fighter bombers in 1943-45 in 609 Sqn as Ken Adam.
Quite a few "enemy Aliens" were recruited into intellicence services for tactical radio interception
- Sydney Goldburg, was born and raised in Leipzig, but held a Polish passport. He served in the Y service - radio interception and was on a fighter direction ship off Normandy on D Day.
Horst Adolf Herzberg born in Berlin in 1991 served in the RN on HMS Bellona as Writer EWilliam Ashley Howard intercepting and translating traffic from German ships at sea.
42 year old WW1 veteran of the KuK Richard Lehniger was perhaps too old to be messing about in boats, but the inscription [on his grave suggests his motivation - its the last line of the original version of the Internationale, the Communist anthem.
By 1943 it was obvious that the internned Germans were not a bunch of Fifth Columnists and many joined the services.
Leo Horn (Leo Schwarz) from Berlon served in 5th Bn Wiltshires from June 1944 to the end of the war.
Ernest Goodman (Ernst Guttmann) served in 5th Battalion Coldstream Guards in the Guards Armoured Division,
Several became Sassenach Scots...
Guy Bishop (Günter Gustav Brüg,served in 7th Battalion the Black Watch 1944-45
Viennese Jew Likwornik born 1924 served in 1st Bn Gordon Highlanders from June 1944-the end of the war.
Ronald Walters (Rudolf Walter, born in Breslau) another kinder transport refugee served in 7th Bn Argyll and Sutherland Highlanders
1RTR and 8 Hussars seem to have received quite a few Austrian and German reinforcements to bring their units up to mstrength prior to D Day.
