General Corral, who had treated with him for peace, was soon to pay the penalty for his readiness to make terms with an invader. He was arrested for treason, on some charge brought by Walker, tried before a court-martial at which the new generalissimo presided, sentenced to death, and executed without delay.
The next event in this fantastic drama of filibusterism was a war with the neighboring republic of Costa Rica. Both sides mustered armies, and a hostile meeting took place at Guanacaste, on March 20, 1856, in which Walker was worsted. He kept the field, however, and met the foe again at Rivas, on April 11. This time he was victorious, and the two republics now made peace.
His military success seemed to have made the invader securely the lord and master of Nicaragua, and he now threw aside his earlier show of modesty and had himself elected president on June 25. He had so fully established himself that he was recognized as head of the republic by President Pierce, on behalf of the United States. But he immediately began to act the master and tyrant in a way that was likely to bring his government to a speedy end.
Money being scarce, he issued currency on a liberal scale, and by a decree he restored the system of slavery which had been abolished thirty-two years before. Not content with these radical measures within the republic itself, he was unwise enough to create for himself a powerful enemy in the United States by meddling with the privileges of the Vanderbilt Steamship Company, then engaged in transporting the stream of gold-hunters to California over a Nicaraguan route. Walker revoked their charter and confiscated their property, thus bringing against his new government a fire in the rear.
His aggressive policy, in fact, made him enemies on all sides, the Central American states bordering on Nicaragua being in sore dread of their ambitious neighbor, while the agents of the Vanderbilt Company worked industriously to stir up a revolt against this soaring eagle of filibusterism.
The result was a strong revolt against his rule, and he soon found himself confronted by a force of[pg 313] patriots in the field. For a short time there were busy times in Nicaragua, several battles being fought by the contending forces, the war ending with the burning of Granada by the president. Finding that the whole country was rising against him and that his case had grown desperate, Walker soon gave up the hopeless contest and surrendered, on May 1, 1857, to Commodore C. H. Davis of the United States sloop-of-war "St. Mary," who took him to Panama, where he made his way back to the United States.
Thus closed the conquering career of this minor Cortez of the nineteenth century. But while Walker the president was no more, Walker the filibuster was not squelched. The passion for adventure was as strong in his mind as ever, and his brief period of power had roused in him an unquenchable thirst for rule. In consequence he made effort after effort to get back to the scene of his exploits, and rise to power again, his persistent thirst for invasion giving the United States authorities no small trouble and ending only with his death.
In fact, he was barely at home before he was hatching new schemes and devising fresh exploits. To check a new expedition which he was organizing in New Orleans, the authorities of that city had him arrested and put under bonds to keep the peace. Soon after that we find him escaping their jurisdiction in a vessel ostensibly bound for Mobile, yet making port first in Central America, where he landed on November 25, 1857.
This effort at invasion proved a mere flash in the pan. No support awaited him and his deluded followers, and in two weeks' time he found it judicious to surrender once more to the naval authorities of the United States; this time to Commodore Paulding, who took him to New York with his followers, one hundred and thirty-two in number.
His fiasco stirred up something of a breeze in the United States. President Buchanan had strongly condemned the invasion of friendly territory in his annual message, but he now sent a special message to Congress in which he equally condemned Commodore Paulding for landing an American force on foreign soil. He decided that under the circumstances, the government must decline to hold Walker as a prisoner, unless he was properly arrested under judicial authority. At the same time Buchanan strongly deprecated all filibustering expeditions.
