Mabel Annie St Clair Stobart (née Boulton; 3 February 1862 – 7 December 1954) was a British suffragist and aid-worker.

Born to a wealthy family, in 1862 in England, her parents were Sir Samuel Bagster Boulton and Sophia Louisa (née Cooper).

Her husband's financials started failing in 1902, and the family moved to Transvaal, in 1903, to set up a farm, in the aftermath of the Boer War.

Stobart approached Buxton at a club and he suggested she travel with him in a few days to make her case directly to the Bulgarian government.

After giving an impassioned speech about British women, Stobart was granted permission for her unit to come and be "...near the front as possible".

The book, War and women, from experience in the Balkans and elsewhere, was dedicated to the Tsaritsa (Queen) of Bulgaria, Eleonore Reuss of Köstritz.

Stobart travelled to Brussels on 18 August 1914, arriving on the evening of the 19th, and sent a cable instructing the unit to come out immediately.

After persistent effort, Stobart was able to gain a passport from the German General, to Venlo in Holland, leaving at 6 p.m. on 24 August, reading Louvain (Leuven) at 8pm, and travelling on the next morning at 5 a.m. (Louvain was destroyed the following day) to Hasselt at 8 a.m. After taking breakfast the motorcade would not restart, and upon repeated inspection of their passports, they were arrested as spies, surrounded by soldiers who were ordered to cock rifles, fix bayonets, and shoot if they moved or talked to each other.

There, an anti-English commanding officer whom Stobart labelled the 'devil-major' stated that a map and camera were enough for them to be condemned as spies, for whom the fate was to be shot within twenty-four hours.

They spent the night, after arguing to not be separated as women were not allowed to sleep with men (the party consisting of her husband, the chaplain and a poor Belgian chauffeur who had been caught up in the affair).

A sympathetic officer, who was married to an English woman, entered the room, and promised to do everything in his power to help, in return for conveying to his wife that all was well for him.

The following morning, the devil major, frustrated by intervention in his planned dawn entertainment of an execution, irately made arrangements to transfer the four prisoners to Cologne to be tried for high treason.

The following evening, she was brought before the judge in the prison, who offered her to board in a hotel, if she gave her word not to attempt to escape, while he investigated her statements.

Stobart answered that she would, only if her companions were extended the same courtesy, to which she was told that they already had done so, and was courteously taken to the hotel, and allocated an officer to supervise their parole.

After some confusing telegrams, their innocence was decided, and upon asking of their desired destination, the judge allowed them to return to London, via Flushing.

[12] On return to London, Stobart then took her unit to the siege of Antwerp, in response to a request received via Lord and Lady Esher.

As a result of the war and its effects, epidemic typhus broke out in Serbia, causing the death of around 150,000 people including about half of the doctors in the country.

The retreat was a complete shambles with terrible cold weather, mud-bound roads, constant enemy attacks, and lack of food and other supplies.
