Southern Front
Second Battle of the Piave: Violent fighting on Piave. Austro-Hungarians capture ground south-east of Montello and Capo Sile (north-east of Venice). British capture Austro-Hungarian advance in the hills. British 48th Division (922 casualties) after 4 counter-attacks has taken 728 PoWs and buried 576 Austrian soldiers. In Mt Grappa sector Italian Fourth Army restores its line except for 2 peaks, releasing 200 Italian PoWs and c.12 guns. Austrian Army Group Conrad losses 35,026 soldiers. Italian Eighth and Third Army counter-attacks recover some ground including 4 villages south of the Piave. Heavy rain, Italian and RAF attacks and lack of bridging equipment (due to shortage of horses) hinder river crossings.
