Operation Wowser

'Wowser' was a US concentrated air attack by Major General Nathan F. Twining’s 15th AAF against German forces, positions and dumps in northern Italy, especially those around Bologna, in preparation for the 'Craftsman' breakthrough of Lieutenant General Lucian K. Truscott’s US 5th Army in this sector just to the north of the 'Gotisch-Linie' defences (15 April 1945).
