Walter was born in Battersea, London about 1894. It's not known when the family moved to Stockport, but they were certainly in the area in the spring of 1899, when Walter's brother, Victor Moss Brabenetz, was born. They lived with their parents, Rosina and Rudolph at 15 Stopford Street, Edgeley.
Walter worked in the local hatmaking industry until he volunteered for the army in September 1914. After training, the 8th Cheshires embarked for Gallipoli on 26th June 1915. Once landed, the troops were subjected to constant sniper and artillery fire. On 15 August, Walter and his comrades were in positions at Chailak Ridge where, over the next few days, they dug trenches and constructed other defences. The Battalion's War Diary makes no specific reference to the day Walter was killed. As a record of the tour of duty, the Diary notes that the Battalion's snipers "did good work during this period", But it also mentions that "Enemy snipers caused some casualties here to the Battalion".
Later, Captain W H Williams wrote to Walter's family. The letter probably confirms that Walter was shot by the Turkish sniper, "I want to console you by saying that he died instantly and in the discharge of his duty. He was a good boy and his loss is felt by us very dearly. His comrades buried him with full honours last night and chose a nice grave for him where he sleeps well." After the failure of the campaign and the evacuation from the peninsula (in January 1916), the location of many graves became lost of the following three years of war. Walter is now commemorated on the Memorial to the Missing on the tip of the Gallipoli peninsula.
More devastating news for Rosina and Rudolph would come in 1918, when they received notification that that their only surviving son, Victor, had been killed on 6 November. The War ended 5 days later.
