Hello,

I have the following info :

HAELEN : On the 17.03.1917, this Belgian ship (°1893, ex-IRENE), was intercepted by a U-boot and severely damaged by gun (Pos 56°15 N – 5°32 W), but could reach Stavanger for refit. 5 casualties.
Intercepted again on the 3 November 1917, this time by UB-63 (Pos. 60°09 N-02°40 E) and leaded to Swinemünde were she was seized.
Was later used as “transport ship” for the Kaiserliche Marine.
Returned on the 13 January 1919 to her former shipping C° : “Compagnie Nationale Belge de Transport Maritime A. Deppe”. Sold in 1925.

TUNISIE : (°1896 ex-SONNENBURG), was also a Belgian cargo belonging to Adolf Deppe C°.
On the 17 .03.1917, she was intercepted by a U-boot (Pos 56°15 N- 5°32 E) while sailing on ballast from Rotterdam to New York, but could reach Stavanger for refit. After the war she still was running by the same Belgian company until 1927.

Source : a recently published book in Belgium (in French and Dutch) about the history of the Belgian Merchant Marine during 1914-18.

Hope this helps.
Regards,
Freddy.
