The wall ran to a circumference of just over 11 miles, and the town had means of maintaining those within it indefinitely. Herds of cattle and sheep, and wide grazing grounds for raising more, acres on which were grown corn and wheat, gave a supply of food far in excess of requirements and made a siege, even were an army available for an investment, a futile proceeding. Could Sir Frederick but bring the Emir to a peaceful frame of mind tremendous dangers would be avoided. But the Emir treated all overtures with contumely or open defiance and provocation. Still, the High Commissioner cultivated patience. An unsuccessful attack on Kano would be immediately followed by a rising of the most powerful Moslem Provinces. Some who had made their submission were suspect, and others were merely waiting to see whether Kano, to which their eyes were turned, and on which their hopes rested, would be able to defy the new Power which had established itself in the southern Provinces. An event took place which brought the situation to a climax. The Magasi—Viceroy—of Keffi murdered a British Resident with his own hands and fled to Kano. The Emir challenged the High Commissioner, not only by giving the murderer refuge but by providing him with a house and according him the place of honour on the Emir’s right hand in royal and public processions. That was in 1902, and if there were any remaining doubts of the sentiments of the Emir they were swept away by his organising an expedition and marching at the head of it to attack the British garrison at Zaria, only 90 miles to the south, in November of the same year. Perhaps fortunately for us, the Emir and his armies turned back, on word reaching him that the Emir of Katsena refused to be drawn into the enterprise. But possibly others might, especially if they saw the now defiant, truculent Emir of Kano not only flouting the High Commissioner but actually taking steps to overrun a Province in which his representatives had been accepted and over which the British flag flew. Unless the whole country was to remain in a condition of ferment, unrest and apprehension, clearly there was only one course for the High Commissioner, and that was to strike, if he could. He determined to make the attempt. As many troops as could be collected—as could be spared from other parts—were assembled at Zaria. They were exclusively Protectorate soldiers, for quickness in delivering the blow was a great factor towards the chance of success. The force was made up of 550 infantry, 101 mounted infantry, 71 artillerymen with 475 mm. guns and 4 Maxims, and the following Europeans: 24 officers, 2 doctors, 12 non-commissioned officers. Colonel Morland, D.S.O., was in command. On the night of February 2 the column camped at the Shallawa River, 6 miles from Kano and next morning advanced on Kano, leaving the carriers in a zariba guarded by 2 officers and 75 men.
