On the evening of the 2nd of June the whole of the Volunteer Force not already called out or enumerated in the above-mentioned lists, was placed on active service, and on Sunday, the 3rd of June, the Province had more than 20,000 men under arms, besides the numerous companies of Home Guards. The entire force turned out not only willingly, but eagerly, although at a season of the year when their business interests suffered greatly by their absence. It was enough for every militia man to know that the country needed his services, and personal interests were cheerfully sacrificed. Instances of devotion to Queen and country were general. Business matters were but a secondary consideration. Merchants and their clerks left their shops, students their colleges, professional men their offices, while factories were shut down and farmers left their ploughs in the furrows to take up their rifles to assist in the national defence. Those who were obliged by age or infirmities to stay at home were not idle, but nobly did their part in raising funds to assist the families of those bread-winners who had gone to serve on the frontier posts. All over the country large sums were raised for this purpose, and the patriotic Relief Committees were exceptionally busy attending to the proper distribution of food and supplies, both among the volunteers and the needy families who were depending upon them. In the order calling out the troops for active service the Governor-General placed the whole force under the command of Lieut.-Gen. Sir John Michel, and added: In former times the Commander-in-Chief has had occasion to call for the active services of the volunteer force to maintain international obligations, and as a precaution against threatened action. These threats have now ripened into actual fact. The soil of Canada has been invaded, not in the practice of legitimate warfare, but by a lawless and piratical band in defiance of all moral right, and in utter disregard of all the obligations which civilization enforces on mankind. Upon the people of Canada this state of things imposes the duty of defending their altars, their homes and their property from desecration, pillage and spoilation. The Commander-in-Chief relies on the courage and loyalty of the volunteer force and looks with confidence for the blessings of Providence on their performance of the sacred duty which circumstances have cast upon them.
