The Battle of Passchendaele (Third Battle of Ypres, Flandernschlacht and Deuxième Bataille des Flandres) 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 miles (8.0 km) 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.
Further operations and a British supporting attack along the Belgian coast from Nieuwpoort, combined with Operation Hush (an amphibious landing), were to have reached Bruges and then the Dutch frontier. The resistance of the 4th Army, unusually wet weather, the onset of winter and the diversion of British and French resources to Italy, following the Austro-German victory at the Battle of Caporetto (24 October – 19 November), enabled the Germans to avoid a general withdrawal, which had seemed inevitable in early October. The campaign ended in November, when the Canadian Corps captured Passchendaele, apart from local attacks in December and the new year. In 1918, the Battle of the Lys and the Fifth Battle of Ypres were fought before the Allies occupied the Belgian coast and reached the Dutch frontier.
A campaign in Flanders was controversial in 1917 and has remained so. The British Prime Minister, David Lloyd George, opposed the offensive, as did General Ferdinand Foch the French Chief of the General Staff. Field Marshal Sir Douglas Haig, commanding the British Expeditionary Force (BEF), did not receive approval for the Flanders operation from the War Cabinet until 25 July.

「右側面下部の中央に取り付けられている」という意味なのですね。 and centeredという文法がわかりませんが、supportが「取り付けられる」という意味がわかれば意味がわかりました。
