Spindler entered nursing in 1911 at the City Fever Hospital, Wakefield and trained at Leeds Township Infirmary from 1912 to 1915.

[4] She joined the Queen Alexandra's Imperial Military Nursing Service (QAIMNS) in October 1915.

To join the Queen Alexandra's Imperial Military Nursing Service it was necessary to be single or recently widowed, to have completed a three-year training course in a hospital approved by the War Office and to be over 25 years old; Spindler was only 24 at the time she signed up.

This CCS specialised in abdominal, chest and thigh wounds which needed urgent treatment and so was stationed relatively close to the front line.

In a letter home, Sister Kate Luard[b] recalled: Bits came over everywhere, pitching at one's feet as we rushed to the scene.

[6]The British Journal of Nursing on 8 September 1917[7] stated: Private communications from Abbeville state that the hospital was shelled all day, that Miss Spindler was struck at 11 a.m., became unconscious immediately and died twenty minutes later in the arms of Nurse Wood of Wakefield, which is also Miss Spindler’s native city, her father being inspector of police.

Miss Spindler was very popular during her training, and her loss is deplored by the many friends she made who deeply sympathise with her family in their sorrow.

The condolence card on General Gough's wreath read 'with deepest respect' and was sent to her mother on 3 September.
