After 1846 and the disintegration of the Tory party over Peel's adoption of free trade, Lord Lyndhurst did not attend parliament sessions as often, but he continued to take a lively interest in public affairs and to make speeches. His address to the House of Lords on 19 June 1854, on the war with Russia, made a sensation in Europe, and throughout the Crimean War he was a strong advocate of the energetic prosecution of hostilities. In 1859 he denounced Napoleon III. His last speech was delivered in the House of Lords at the age of eighty-nine.
