The British and Austrian navies subsequently blockaded the Nile Delta and bombarded Beirut on 11 September 1840. On 26 September, Friedrich, commanding the Austrian frigate "Guerriera", bombarded the port of Sidon with British support. The Austrians and British landed in the city and stormed its coastal fortifications, capturing it on 28 September. After capturing Sidon, Austria's naval squadron sailed on to Acre which bombarded the city in November, destroying its coastal fortifications and silencing the city's guns. During the storming of the city, Friedrich personally led the Austro-British landing party and hoisted the Ottoman, British, and Austrian flags over the Acre's citadel upon its capture. For his leadership during the campaign, Archduke Friedrich was awarded the "Knight of the Military Order of Maria Theresa". In 1844, Archduke Friedrich was promoted to the rank of Vice-Admiral and become Commander-in-Chief of the Navy at the age of 23, but his tenure as the head of the Austrian Navy ended just three years after his appointment when he died in Venice at the age of 26.
