Malam Fatori- Surveying the charred ruins of the northern Nigerian town of Malam Fatori, which Chadian troops and his own soldiers from Niger liberated from Boko Haram last week, Colonel Toumba Mohamed paused to reflect on Nigeria's landmark election.
As the two nations' forces poured into the border town on Tuesday, driving out the Islamist fighters, Nigeria's election commission was announcing the victory of opposition candidate Muhammadu Buhari.
"We hope that finally the armies of Chad and Niger will be able to fight Boko Haram side by side with the Nigerian army," said Toumba, who expects to see changes when Buhari, a former general and Muslim from the north, is sworn in.
Boko Haram's six-year insurgency in northern Nigeria, and incumbent President Goodluck Jonathan's failure to decisively counter the threat, were a key issue in the Nigerian election.
Gains by the Islamist movement, which is seeking to carve a caliphate out of Nigeria's northeast, even forced a poll delay as a regional force launched an offensive to drive them back.

But it has been Chad's battle-hardened troops, and not Nigeria's, that have led in the offensive, expelling Boko Haram from the major towns in the north in just a matter of weeks.
Malam Fatori - seized by Boko Haram in November in fighting that sent hundreds of Nigerian troops stationed there fleeing into Niger - was one of the group's last border footholds.
The fall of the town marked the end of the first phase of regional action, General Seyni Garba, Niger's army chief of staff, told private Niger television station Ténéré.
"The second phase is to secure the whole of the conquered territory with mopping up operations everywhere that Boko Haram can be found. We need to be able to secure the whole of the Lake Chad basin," he said on Sunday.
Buhari has called Nigeria's reliance on neighbouring armies a disgrace and has vowed to restore the territorial integrity of Africa's most populous nation. There is still work to be done.

Boko Haram set Malam Fatori on fire before withdrawing to the former Nigerian army camp outside of town to dig in and fight. In clashes on Wednesday, 170 militants were killed, while nine Chadian soldiers died and another 16 were wounded.
"Boko Haram no longer has a stronghold. But they are still a threat that must be cleaned up," General Seyni Garba, the head of Niger's army, said during a visit to Malam Fatori on Friday.
To date, problems of communication and coordination have stymied military cooperation between Nigeria and its neighbours.
But it has also struggled to overcome distrust between armies that have not always fought on the same side. Chad occupied parts of Nigeria's north in the 1980s. Chad army chief General Brahim Seid Mahamat said on Friday times have changed.
"We came here to help our brother country. When they come to take control of the towns we've liberated, we'll leave.
