Preparations then began for the final battle on the Italian Front, the stunning success of the Battle of Vittorio Veneto. The British were relieved in the Asiago sector and moved to join the British-commanded Tenth Italian Army near Treviso. 24th HAG supported a number of British and French raids during September and October, then on 23 October the preliminary attacks began, supported by 24th HAG's howitzers. The main British assault crossed the River Piave on 27 October, with the heavy guns engaging all known Austrian gun positions and providing a protective barrage on either flank. A bridge was ready by 29 October and the heavy guns crossed the river. By 1 November the Austrian army had collapsed and the pursuing British troops had left their heavy guns far in the rear. Austrian signed the Armistice of Villa Giusti on 3 November, ending the war in Italy.
