The whole number was estimated to be about 1,500 men, who were principally veteran soldiers of the Northern and Southern armies. This was the "forlorn hope" who were expected to make the first landing and hold the country until sufficient reinforcements could be rushed across the border to enable them to make a success of the campaign. Buffalo was full of Fenians and their sympathizers at that time, and thousands were coming into the city every day to take part in the invasion. It was an opportune time for such a movement, as the popular feeling of the American people was not altogether amicable or friendly to the British nation, and it was the hope of the promoters of the raid that something might occur which would give them the countenance and support of the United States. It is a well-known fact that under the political system of America the Irish vote is a dominant factor in elections, and all classes of citizens who aspire to public office are more or less controlled by that element. Consequently the vigilance of many of Uncle Sam's officials was relaxed, and they winked the other eye as the invaders marched towards Canada, instead of endeavoring to stop them from committing a breach of the law of nations in regard to neutrality. It was asserted in the public press of the United States and proclaimed by the Fenians themselves at that time, that Andrew Johnson (who was then President of the United States) and Secretary of State Seward openly encouraged the invasion for the purpose of turning it to political account in the settlement of the Alabama Claims with Great Britain. In view of the fact that he held back the issuance of his proclamation forbidding a breach of the Neutrality Act for _five full days after_ the Raid had been made, there was manifestly some understanding between President Johnson and the Fenian leaders, as the American authorities were perfectly cognizant of what was intended long before Gen. O'Neil crossed the boundary, and might have been prevented from doing so, had the United States officials at Buffalo exercised such due vigilance as Gen. Meade did in the Campo Bello affair.
