In 1849, Salvador became involved in a quarrel with the British chargé d'affaires, Chatfield, resulting from alleged claims preferred by him with his usual haughtiness, on behalf of fellow-subjects of his. Vasconcelos' government looked on these claims as unjust, and refused them recognition. Chatfield then caused the blockading by a naval force of La Union, the port from which Salvador derived the greater portion of her revenue.[XIV-43] Unable to resist, her government agreed on the 12th of November, 1849, to acknowledge the indebtedness, and make provision for its payment. The blockade was then raised.[XIV-44] But this did not end the disagreements between Chatfield and the Salvador government. On the 6th of August he made peremptory demands,[XIV-45] coupled with a menace that if not complied with at once the coasts of the state would be blockaded by British war ships then coming to act under his instructions. The government of Salvador did not comply with the demands,[XIV-46] and on the 16th of October port La Union was blockaded by the British ship _Champion_, whose commander notified the authorities that if within ten days full satisfaction were not given for the insults to the British flag, the blockade would be extended to the whole coast, another vessel being despatched to Acajutla to enforce it. No satisfaction having been given as demanded, that menace was carried out. The difficulties remained unsettled in the latter part of February 1851, though the British war vessels had retired.[XIV-47] But they were subsequently arranged in an amicable manner. With the exception of these troubles, and the repeated differences with the other states of Central America, Salvador has maintained friendly relations with foreign powers, most of which have treaties with her on terms satisfactory to all concerned.[XIV-48] * * * * * [Sidenote: MULTIPLIED HOSTILITIES.] Vasconcelos was not more successful in preserving peace within the state than in forcing Guatemala to abandon the policy she had adopted of maintaining an absolute autonomy. In his invasion of that neighbor's territory early in 1851, as we have seen in the previous chapter, he was worsted, which roused popular indignation against him, followed by a revolt, and his deposal by congress.[XIV-49] On the 1st of March, the substitute, J. F. Quiroz, was called to occupy the executive chair, and did so.[XIV-50] The president for the constitutional term 1852-3 was Francisco Dueñas, who succeeded in settling the differences existing between Salvador and Guatemala.
