In the United States, O'Mahony's presidency over the Fenian Brotherhood was being increasingly challenged by
William R. Roberts. Both Fenian factions raised money by the issue of bonds in the name of the "Irish Republic", which were bought by the faithful in the expectation of their being honoured when Ireland should be "
A Nation Once Again". These bonds were to be redeemed "six months after the recognition of the independence of Ireland". Hundreds of thousands of Irish immigrants subscribed. by
Currier & Ives, New York, c. 1866 Large quantities of arms were purchased, and preparations were openly made by the Roberts faction for a coordinated series of raids into Canada, which the United States government took no major steps to prevent. Many in the US administration were not indisposed to the movement because of Britain's actions of what was construed as assisting the Confederacy during the
American Civil War, such as
CSS Alabama and
blockade runners smuggling in weapons. Roberts' "Secretary for War" was General
T. W. Sweeny, who was struck off the American army list from January 1866 to November 1866 to allow him to organise the raids. The purpose of these raids was to seize the transportation network of Canada, with the idea that this would force the British to exchange Ireland's freedom for possession of their Province of Canada. Before the invasion, the Fenians had received some intelligence from like-minded supporters within Canada but did not receive support from all Irish Catholics, as there those who saw the invasions as threatening the emerging Canadian sovereignty. In April 1866, under the command of
Bernard Doran Killian, a band of more than 700 members of the Fenian Brotherhood arrived at the Maine shore opposite
Campobello Island with the intention of seizing it from the British. British warships from Halifax, Nova Scotia were quickly on the scene and the show of military force dispersed the Fenians. This action served to reinforce the idea of protection for New Brunswick by joining with the
British North American colonies of
Nova Scotia,
Canada East, and
Canada West in
Confederation to form the
Dominion of Canada. The command of the expedition in
Buffalo, New York, was entrusted by Roberts to Colonel
John O'Neill, who crossed the
Niagara River (the Niagara is the international border) at the head of at least 800 (O'Neill's figure; usually reported as up to 1,500 in Canadian sources) men on the night and morning of 31 May/1 June 1866, and briefly captured
Fort Erie, defeating a Canadian force at
Ridgeway. Many of these men, including O'Neill, were battle-hardened veterans of the
American Civil War. In the end, the invasion had been broken by the US authorities' subsequent interruption of Fenian supply lines across the Niagara River and the arrests of Fenian reinforcements attempting to cross the river into Canada. It is unlikely that with such a small force they would have ever achieved their goal. Other Fenian attempts to invade occurred throughout the next week in the
St. Lawrence Valley. As many of the weapons had in the meantime been confiscated by the US army, relatively few of these men actually became involved in the fighting. There even was a small Fenian raid on a storage building that successfully got back some weapons that had been seized by the US Army. Many were eventually returned anyway by sympathetic officers. To get the Fenians out of the area, both in the St. Lawrence and Buffalo, the U.S. government purchased rail tickets for the Fenians to return to their homes if the individuals involved would promise not to invade any more countries from the United States. Many of the arms were returned later if the person claiming them could post bond that they were not going to be used to invade Canada again, although some were possibly used in the raids that followed. In December 1867, O'Neill became president of the Roberts faction of the Fenian Brotherhood, which in the following year held a great convention in
Philadelphia attended by over 400 properly accredited delegates, while 6,000 Fenian soldiers, armed and in uniform, paraded the streets. At this convention, a second invasion of Canada was conceived. The news of the
Clerkenwell explosion was a strong incentive to a vigorous policy. At the time,
Henri Le Caron, a
mole for
British Intelligence, held the position of "Inspector-General of the Irish Republican Army". Le Caron later asserted that he distributed fifteen thousand stands of arms and almost three million rounds of ammunition in the care of the many trusted men stationed between
Ogdensburg, New York and
St. Albans, Vermont, in preparation for the intended raid. It took place in April 1870 and proved a failure just as rapid and complete as the attempt of 1866. The Fenians under O'Neill's command crossed the Canadian frontier near
Franklin, Vermont, but were dispersed by a single volley from Canadian volunteers. O'Neill himself was promptly arrested by the United States authorities acting under the orders of President
Ulysses S. Grant. After resigning as president of the Fenian Brotherhood, John O'Neill unsuccessfully attempted an unsanctioned raid in 1871 and joined his remaining Fenian supporters with refugee veterans of the
Red River Rebellion. The raiding party crossed the border into
Manitoba at
Pembina,
Dakota Territory and took possession of the
Hudson's Bay Company trading post on the Canada side. U.S. soldiers from the fort at Pembina, with permission of Canadian official
Gilbert McMicken, crossed into Canada and arrested the Fenian raiders without resistance. The Fenian threat prompted calls for
Canadian confederation. Confederation had been in the works for years but was only implemented in 1867, the year following the first raids. In 1868, a Fenian sympathiser assassinated
Irish-Canadian politician
Thomas D'Arcy McGee in Ottawa, allegedly in response to his condemnation of the raids. Fear of Fenian attack plagued the
Lower Mainland of
British Columbia during the 1880s, as the Fenian Brotherhood was active in both
Washington and
Oregon, but no raids ever materialized . At the inauguration of the mainline of the
Canadian Pacific Railway in 1885, photos taken of the occasion show three large
British warships sitting in the harbour just off the railhead and its docks. Their presence was explicitly because of the fear of Fenian invasion or terrorism, as were the large numbers of troops on the first train. ==1867 and after==
