Service Life:


Unit / Ship / Est.: 1/The Buffs (East Kent Regiment) 

1st Battalion August 1914 : in Fermoy. Part of 16th Brigade, 6th Division

Action : The Battle of Festubert 

Festubert (15-25 May 1915) was really a continuation of the Battle of Aubers Ridge that had been called off on 10th May, and in places fought over the same ground with the same depressing outcome. Some minor tactical success was achieved but it did not justify the 16,000 casualties. It did however reinforce the lessons of Neuve Chapelle and Aubers Ridge and conditioned planning and thinking that evolved into the tactical planning of the Somme in 1916.

Detail :

Roger Cecil Slacke (also known as Rory) was born in Ireland in 1880, the son of Sir Owen Slacke. He went to Repton and Cambridge. He joined the Buffs from the militia in 1902 (6th Royal Irish Rifles), serving in Burma, India and Aden. He married Violet in 1910 and they had a child in 1912. He went overseas on 25/11/1914 as a Captain and joined his Battalion on 3/12/14. He was killed whilst attached to the 2nd Queen's on 16/5/15 and was originally buried in an orchard near Festubert. A story in the Dundee Advertiser of August 1918 relating a story from a David Grant of Freuchie, near Falkland in Fife, Scotland, who said that just before the Battle of Festubert on 5 June 1915, "the grave of an officer of the Buffs attached to the West Surreys brought memories of Falkland again. Out into the devastation of No Man's land, he (David Grant) crawled, heedless of danger. It was the tomb of Major Slacke. Reverently he marked it out, and returned again to lay upon it the floral offerings which other soldiers from devoted Fife had brought from villages behind the lines." He was re-interred after the war and is one of seven Freemasons buried in Guards Cemetery, Windy Corner, Cuinchy.

Roger Cecil Slacke is listed amongst the names within the 1921 and 1933 workings of the Masonic Roll of Honour, however, his name is not found in the contribution records of Quadratic, under which Lodge he is recorded. He does not appear to be listed under the English or Irish Constitution, and so provides a masonic mystery as to where and when he was initiated and under what circumstance.
