Following the revolutionary events of 1848, the cry became louder in all German states for the creation of a purely German navy ("Deutsche Marine"), which was founded on 4 June 1848 as the "Reichsflotte". In a letter of July 23, 1848 to Heinrich von Gagern, President of the Frankfurt National Assembly, Brommy offered his help in building up a German fleet. In a reply of November 4, 1848, he was directed by Commerce Minister Duckwitz to come to Frankfurt am Main, where Brommy arrived at the end of the year.
