The 1929 economic crisis which began in the US affected the German shipping companies. The NDL and the HAPAG therefore entered into a cooperation agreement in 1930, and beginning in 1935, instituted joint operations in the North Atlantic. The first signs of a merger were visible. By 1932, the NDL was in an economic crisis, with about 5,000 employees let go, salary cuts, and red ink. Glässel was dismissed. The government placed both NDL and HAPAG in trusteeship under Siegfried Graf von Roedern, and following the death of Stimming, Heinrich F. Albert briefly became head of the NDL, followed after some eighteen months by the National Socialist Rudolph Firle. Bremen State Councillor Karl Lindemann was Chairman of the Board from 1933 to 1945. A programme of economic recovery by divestments and restructuring was initiated. HBAL and the Roland Line became independent companies once more, and other lines took over services to Africa and the Mediterranean. The Nazi regime ordered both NDL and HAPAG to relinquish ships to other lines which were to operate in their regions without competition from other German companies, in particular to Hamburg Süd, the Deutsche Afrika-Linien and the Deutsche Levante Linie.
