ascended to the crown of Hanover, he replaced their uniforms with Prussian Army-style ones, which included the pickelhaube spiked helmet for his Guard Corps. By 1866 they wore a more Austrian style of uniform, with only the guard corps keeping the Prussian one. During the Austro-Prussian War, the Hanoverian Army fought and defeated the Prussians during its march south towards Austria, at the Battle of Langensalza. However, it was later surrounded and forced to surrender to Prussia. Standard, ensign and coat of arms After the personal union with the United Kingdom ended in 1837 with the accession of Queen Victoria, Hanover kept the British royal arms and standard, only introducing a new Crown (after the British model). The centre of this coat of arms and royal standard included the original arms of Hanover, which consisted of the two lions of the Brunswick, the rampant lion with hearts of Lüneburg and the horse of Hanover itself, surmounted by the Imperial Crown of the Holy Roman Empire for the Holy Roman office of Archbannerbearer/Archtreasurer). As Hanover no longer was ruled by the British monarchs, the arms of Hanover was simultaneously removed from the British coat of arms and royal standard, so it was no longer identical with that of the Kingdom of Hanover.
