Camillo di Cavour, under orders of Victor Emmanuel II of Piedmont-Sardinia, sent an expeditionary corps of 15,000 soldiers, commanded by General Alfonso La Marmora, to side with French and British forces during the war.:111–12 This was an attempt at gaining the favour of the French, especially when the issue of uniting Italy would become an important matter. The deployment of Italian troops to the Crimea, and the gallantry shown by them in the Battle of the Chernaya (16 August 1855) and in the siege of Sevastopol, allowed the Kingdom of Sardinia to be among the participants at the peace conference at the end of the war, where it could address the issue of the Risorgimento to other European powers.
