'Veilchen' (ii) was a German naval minelaying operation in the Pechora Sea by Kapitänleutnant Helmut Vogler’s U-212 (26 July/4 August 1943).

On 5 August the 80-ton Soviet motor vessel Mayakovsky struck one of the 16 TMC mines laid in this undertaking near Sengeysky island in the Pechora Sea, and was destroyed in the resulting explosion.
