Battle of Passchendaele Why did Haig launch an offensive here?  Haig wanted to launch an offensive on Flanders. This was following a warning that that the German blockade would cripple the British attack. Haig wanted to reach the Belgian coast so that he could destroy the submarine bases that were situated there. This was also being launched because there was a possibility of a Russian withdrawal from the war. This would then let the Germans redeploy from the Eastern front which would then increase their reserve strength dramatically. (douglas haig) What were the strategies and tactics used to plan for success?  Douglas Haig belived that the British were on the verge of a breakthrough. He planned to attack the Germans lines just outside Ypres, Belgium and would be the 3rd battle of Ypres, the others being in 1914 and 1915. He planned that once they had broke through they would sweep across the low plains and swing north to the sea.  On the morning of June 7, 1917, the allies set of a series of giant land mines under the German lines south-east of Ypres, this disrupted and disorganized German defensive positions. This planned was initiated successfully but the severe wet weather affected the British and the men were bogged in mud that was like quicksand. Haig plan had became another failure.
