The Capture of Westhoek (10 August 1917) took place on the Gheluvelt Plateau near Ypres in Belgium, during the Third Battle of Ypres (31 July – 10 November 1917), in the First World War.
 The British Fifth Army attacked the Gheluvelt Plateau at the Battle of Pilckem Ridge (31 July – 2 August) but the German 4th Army had fortified its positions in the Ypres Salient since the Second Battle of Ypres (22 April – 25 May 1915).
 The British reached the first objective in the south and the second objective on the northern flank, then lost some ground to German counter-attacks.
 Another attack on 2 August was postponed due to torrential rain from the afternoon of 31 July until 5 August.
The Third Battle of Gaza was fought on the night of 1/2 November 1917 between British and Ottoman forces during the Sinai and Palestine Campaign of World War I, and came after the Egyptian Expeditionary Force (EEF) victory at the Battle of Beersheba had ended the Stalemate in Southern Palestine.
 The fighting occurred at the beginning of the Southern Palestine Offensive, and together with attacks on Hareira and Sheria on 6–7 November and the continuing Battle of Tel el Khuweilfe which had been launched by General Edmund Allenby on 1 November, it eventually broke the Gaza to Beersheba line defended by the Yildirim Army Group.
 Despite having held this line since March 1917, the Ottoman Army was forced to evacuate Gaza and Tel el Khuweilfe during the night of 6/7 November.
 Only Sheria held out for most of the 7 November before it too was captured.

Boris Borisovich Glinsky (Russian: Бори′с Бори′сович Гли′нский , 12 October 1860, Saint Petersburg, Russian Empire, – 30 November 1917, Petrograd, Soviet Russia) was a Russian writer, publicist, publisher, editor and politician.
 A prominent historian and biographer, Glinsky published numerous articles and essays, mainly in "Istorichesky Vestnik", which he was also the editor of in 1913–1917, "Severny Vestnik" (editor and publisher in 1890—1891), and "Russkaya Budushchnost" (Russian Future, 1915—1917).
 Described as a 'progressive nationalist', Glinsky supported both the 1917 February Revolution and the Kornilov affair.
 As a result, in August 1917 he was arrested on the counter-revolutionary charges, but in October 1917 was released.
 Glinsky died in Petrograd on 30 November 1917.
The Battle of Passchendaele (German: "Flandernschlacht" , French: "Deuxième Bataille des Flandres" ), also known as the Third Battle of Ypres, was a campaign of the First World War, fought by the Allies against the German Empire.
 The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917.
 Passchendaele lay on the last ridge east of Ypres, 5 mi from a railway junction at Roulers, which was vital to the supply system of the German 4th Army.
 The next stage of the Allied plan was an advance to Thourout–Couckelaere, to close the German-controlled railway running through Roulers and Thourout.
The Battle of Caporetto in 1917 (also known as the Twelfth Battle of the Isonzo, the Battle of Kobarid or the Battle of Karfreit as it was known by the Central Powers), took place from 24 October to 19 November 1917, near the town of Kobarid (now in north-western Slovenia, then part of the Austrian Littoral), on the Austro-Italian front of World War I.
 The battle was named after the Italian name of the town (also known as "Karfreit" in German).
