Alimi's response arrived on the ninth day—a day early.
A courier Afonja had never seen before brought it. Young and road-tired, he wore the blue-gray of the northern pastoral communities' formal messenger corps rather than Alimi's household colors. The designation was significant. It meant the letter was not a personal note from Alimi, but an official message from a larger power, delivered through formal channels. It was a far cry from what Afonja had requested or expected.
He carried the letter to the watchtower before unsealing it, wanting the frontier in view while he read.
The letter came from Mallam Usman dan Fodio. Not Alimi, not Abdullahi, nor any mid-level diplomat in the reform movement. It was from the man himself, written in his own hand. The Arabic was clear and precise, penned by someone who knew every word would be scrutinized and had chosen each one accordingly.
It stated five points:
It acknowledged the Ilorin frontier commander's wisdom in seeking direct dialogue rather than waiting for events to force the issue. It noted that the reform movement recognized Ilorin as a community of people rather than just a strategic asset, and that the movement distinguished between communities willing to accept its authority and those that chose resistance. It explained that the terms offered to the former differed vastly from those given to the latter, and that the window to negotiate was governed by circumstances rather than a schedule. It made clear that the movement's advance into the region did not depend on Ilorin's decision and would proceed according to its own theological and military logic.
Finally, the tone shifted to a more personal register. It noted that Abdullahi had spoken well of their correspondence and that a man of Afonja's proven capability would not be wasted in either future—though those futures differed sharply in ways that would soon become clear.
Afonja read it twice, folded it, and turned his gaze back to the frontier.
The northeast was wrong. Having observed the region from this tower for eight months, he recognized the subtle shift the way he knew the air before a storm—an aggregate of small signals forming an unmistakable pattern.
The camps were moving.
He descended the tower and called for Suleiman. Twelve campaigns with the Oyo cavalry had eliminated the hesitation between observation and action. He did not pause to ponder; he moved.
Suleiman met him in the yard, holding the morning's tactical briefing. "The north gate sentries reported an increased dust cloud forty minutes ago," Suleiman said. "I sent riders to confirm."
"How many?"
"The gate estimates a thousand cavalry. Based on the dust, I estimate fifteen hundred to two thousand."
"Composition?"
"Light cavalry, Fulani-style—fast and spread out, not a tight Oyo column. Infantry follows behind, but the cavalry leads."
"Archers?"
"Unconfirmed. The riders will report back."
"Mount the garrison," Afonja ordered. "Every horse fit to move. Form up in the north yard—light horse at the front, heavy cavalry in three columns behind. Close the south gate. Nobody enters or leaves."
He turned toward the stables. "Send a fast rider south using my personal cipher, not the standard route. Pass a single message: The frontier is active. The Aare-Ona-Kakanfo must be informed immediately."
"Why bypass the standard route?" Suleiman asked.
"The standard route is why we are caught unprepared."
Afonja had submitted reports for eight months, but the Bashorun's office in the south had delayed them under review. He would address that failure later; first, he had to deal with the immediate threat.
He reached his horse, Iya. Dispensing with the grooms, he saddled her quickly himself. She stood still, sensing the urgency. When he mounted, she moved straight toward the north yard without instruction.
The garrison assembled in eleven minutes—four hundred and twelve cavalry arrayed in the open-wing formation Afonja had adapted years ago from a Nupe engagement. By trading depth for width, the formation sacrificed center protection to give the wings speed, placing the commander at the front of the center column where the risk was highest.
Afonja took his place at the head of the center.
"The riders have returned," Suleiman reported, riding up beside him. "Fifteen hundred cavalry confirmed. An advance force of four hundred will arrive within thirty minutes. The main body follows."
"They are probing our reaction time," Afonja said.
"They want to see how quickly we form."
"Then we will show them. If they see we are ready, it will force their main body to reassess and buy us time."
They rode north through the city, the four hundred armed cavalry parting the morning street traffic. Bystanders stepped back into doorways, watching in silence. The routine drills were over.
The north gate opened as they approached, and the column passed through onto the road leading toward the open country where the Fulani camps were set.
"We hold the tree line," Afonja ordered as the distant dust cloud came into view. "We do not meet them in the open where they have the speed advantage. The trees will break their formation."
He drew his sword, its familiar weight settling into his grip. Iya adjusted her stride, holding a steady, combat-ready cadence.
"Column, forward," he said.
They advanced at a fast canter, preserving the horses' energy for impact. They reached the transitional bush just as the sound of approaching hooves turned into a roar.
Four hundred Fulani horsemen burst through the trees at a full gallop, spread wide in a loose charge. Twenty yards from Afonja's line, they caught sight of the open wings—a defensive structure completely different from the Oyo columns they anticipated.
The two forces collided. Afonja's front line absorbed the charge across three points, dispersing the impact and shattering the enemy's momentum. The formations interlocked, breaking the clash down into isolated, single-combat engagements.
Afonja rode into the center of the fray. Four years away from combat had changed nothing; instinct took over, his blade finding its targets with effortless precision.
In the heat of the fight, two thoughts crossed his mind: They are skilled. And: They know we are skilled.
It was only afterward that the final realization struck him: This is the last time we fight as external enemies before one of us absorbs the other.
