Brigadier General Julian Hasler (16 October 1868 – 27 April 1915), was a British Army officer who fought in World War I as a brigade commander before being killed in action.

[1] After the academy, Julian Hasler was commissioned into the 1st Battalion of the East Kent Regiment, on 19 September 1888,[2] and soon promoted to lieutenant on 4 February 1892.

[3] From 1895 he was almost uninterruptedly in active military service, first with the Chitral Relief Force (1895), then the Northwest Frontier in India[4] as a captain (1897-1898, where he participated in the capture of the Tanga Pass), and after being seconded for service under the Colonial Office in June 1899,[5] in South Africa (1900-1902) where he raised the Hasler's Australian Scouts, briefly in Nigeria where he documented a new species of Red-fronted gazelle,[a] and in West Africa (1899-1900, 1903–1910).

On 24 April 1915 it was sent north to reinforce the 5th Corps in the Ypres salient and was subsequently attached to 28th Division, taking over the front line between BERLIN WOOD and FORTUIN.

[13] His commanding officer, Major-General Edward Bulfin, had ordered him to abandon the position after dark on that same day, but he was delayed and was killed around 9pm that evening.
