Napoleonic Wars
The time period of the Napoleonic Wars was 1803 to 1815.
Henry Clinton - Napoleonic Wars - died in 1829.
German campaign - Napoleonic Wars - happened in 1813.
Henry Clinton - Napoleonic Wars - was born in 1771.
Portuguese Legion - Napoleonic Wars - was created in 1808.
There is no real consensus as to when the Napoleonic Wars started, as it could be seen as an extension of the French Revolution. The wars against France started with the First Coalition in 1793 and there were very few years between then and 1815, the end of the wars, when there was not fighting with France somewhere in the world. On his return from fighting in Egypt, Napoleon seized control of the French government on 9 November 1799. This may be the moment the French Wars became the Napoleonic Wars, when Napoleon was controlling all of France. It just depends on your own viewpoint.
