The Austrians began their development of a rocket arm in 1808. Chief Fireworks Master Anton Mager was the head of rocket production and his work was influenced by Congreve's work. Mager successfully tested his rockets in the presence of the Archduke Charles but nothing much else was done with them until an Austrian artillery officer, Major Vincent Augustin, who had been at Leipzig and had witnessed the British rocket battery in action.
He went to Great Britain after Napoleon's first abdication, but the British were close-mouthed on their rocket program. Therefore, Augustin went to Denmark to see their program.
Because of Augustin's work a rocket laboratory and production facility was established at Wienerneustadt near Vienna in May 1815 and produced 2,400 rockets and a rocket battery was also established. It was employed during the Austrian siege of Hunigue in 1815.
The Danes, who had been the target of British rocket fire at Copenhagen in September 1807, developed an effective military rocket under the supervision of Lieutenant Andreas Schumacher, an engineer officer in the Danish army. He copied a recovered English rocket in the mess at Copenhagen and the work he did was successful by 1811. They were put into production and were used against the allies at the siege of Hamburg in 1814 in conjunction with Davout's defense of the city. Schumacher cooperated openly with the French in Hamburg and together they developed functioning rockets.
Other French work was done on rockets after they recovered a Congreve rocket somewhat intact after a British raid on the Ile d'Aix in 1809. A board of officers and French scientists was convened by Napoleon and under the supervision of an army artillery officer, Captain Charles Moreton de Chabrillon, and a naval artillery officer, Captain Pierre Bourree successfully manufactured functioning rockets which were tested at Toulon. Based on those tests, four rocket factories were established at the naval arsenals at Lorient, Rochefort, Brest, and Cherbourg. The intent was to employ the new rockets at sieges and they were used at the siege of Cadiz, but the rockets did not perform as expected and the promising project was dropped.
