The general attitude of Germany, France and Russia toward the Boer mission was guided by a policy of strict adherence to the neutral obligations assumed at the beginning of the war. These Powers in their official statements all followed such a course, realizing that it was demanded by a sound foreign policy. They considered the idea of intervention out of the question, although friendly interest for the Boers and for the peaceful purpose of their mission was evident.
From the beginning of the war the active duties of neutrality had fallen upon Portugal, since neither the Transvaal nor the Orange Free State possessed a seaport. Fifty miles of railway separated the Portuguese harbor of Lorenzo Marques in Delagoa Bay from the Transvaal border, and from this point the road continued to Pretoria. Lorenzo Marques being neutral could not be blockaded, but, being neutral, it was the duty of the Portuguese Government to observe the laws of neutrality. Great Britain alleged that a constant stream of supplies and recruits passed over the Portuguese border to aid the Boer armies. The difficulty on the part of the English Government, however, was to prove that the goods were in fact on their way to a belligerent destination or that small parties of men were in reality organized bands of recruits for the fighting forces of the enemy. It was asserted that the manner in which Portugal performed her neutral obligations, demanding an absolutely impartial treatment of both belligerents, made Delagoa Bay and the port of Lorenzo Marques more valuable to the Republics than would have been the case had they actually been in their possession.

The ammunition was transferred to a Portuguese troop ship, and the Governor assigned as sufficient reason for his action the fact that Great Britain had urged the measure upon the Portuguese authorities. He stated that orders had been received from Lisbon that guns and ammunition for the Transvaal should not be landed until further notice from the Portuguese Government. The Transvaal strongly protested against this act as a breach of
