The French legionaries were undoubtedly of more actual service to the Boers than the volunteers of any other nationality, inasmuch as they were given the opportunities of doing valuable work. Before the war one of the large forts at Pretoria was erected by French engineers, and when the war was begun Frenchmen of military experience were much favoured by General Joubert, who was proud of his French extraction. The greater quantity of artillery had been purchased from French firms, and the Commandant-General wisely placed guns in the hands of the men who knew how to operate them well. MM. Grunberg and Leon were of incalculable assistance in transporting the heavy artillery over the mountains of Natal, and in securing such positions for them where the fire of the enemy’s guns could not harm them. The work of the heavy guns, the famous “Long Toms” which the besieged in Ladysmith will remember as long as the siege itself remains in their memory, was almost entirely the result of French hands and brains, while all the havoc caused by the heavy artillery in the Natal battles was due to the engineering and gunnery of Leon, Grunberg, and their Boer assistants. After remaining in Natal until after the middle of January the two Frenchmen joined the Free State forces, to whom they rendered valuable assistance. Leon was wounded at Kimberley on February 12th, and, after assisting in establishing the ammunition works at Pretoria and Johannesburg, returned to France. Viscount Villebois-Mareuil was one of the many foreigners who joined the Boer army and lost their lives while fighting with the Republican forces. While ranking as colonel on the General Staff of the French army, and when about to be promoted to the rank of general, he resigned from the service on account of the Dreyfus affair. A month after the commencement of the war Villebois-Mareuil arrived in the Transvaal and went to the Natal front, where his military experience enabled him to give advice to the Boer generals. In January the Colonel attached himself to General Cronje’s forces, with whom he took part in many engagements. He was one of the few who escaped from the disastrous fight at Paardeberg, and shortly afterwards, at the war council at Kroonstad, the French officer was created a brigadier-general—the first and only one in the Boer army—and all the foreign legions were placed in his charge. It was purposed that he should harass the enemy by attacks on their lines of communication, and it was while he was at the outset of the first of these expeditions that he and twelve of his small force of sixty men were killed at Boshof, in the north-western part of the Free State, early in April. Villebois-Mareuil was a firm believer in the final success of the Boer
