Kilmaine was involved in quelling the Jacobin Uprising in May, 1795.
 He assisted Jean-Charles Pichegru in the defense of the National Convention against excited mobs of Parisian faubourgs.
 Kilmaine continued to fight for the Convention until the 13th Vendemiaire, 1796, actively co-operating with Napoleon Bonaparte and the Revolutionary Party.

Early in 1796 he set out with Bonaparte on the Italian Campaign.
 He fought at the Battle of Lodi on 10 May and contributed to the victory by leading a cavalry charge.
 In September, he was appointed Commander of Northern Italy.
 This campaign significantly increased his reputation throughout Europe as a truly brilliant officer.

In October, Kilmaine was one of Napoleon's subordinate commanders during the Siege of Mantua.
 The Austrians, who were commanded by Dagobert Sigmund von Wurmser, attempted to breakout and were repulsed with the loss of 1,100 men and five pieces of cannon.
 Kilmaine played a key role in repulsing them.
 Bonaparte, in his dispatch to the Directory on 1 October 1796 wrote:
General Kilmaine, who commands the two divisions which press the siege of Mantua, remained on the 29th ultimo in his former position, and was still in hopes that the enemy would attempt a sortie to carry forage into the place, but instead they took up a position before the gate of Pradello, near the Carthusian convent and the chapel of Cerese.
The brave General Kilmaine made his arrangements for an attack, and advanced in two columns against these two points, but he had scarcely begun to march when the enemy evacuated their camps, their rear having fired only a few musket-shots at him.
The advanced posts of General Vaubois have come up with the Austrian division which defends the Tyrol, and made one hundred and ten prisoners"
Early in December, Wurmser attempted another breakout.
 The Austrians began their operation just before dawn advancing under a furious cannonade.
 However, as Bonaparte noted,  "Kilmaine made him return, as usual, faster than he came out, and took from him two hundred men, one howitzer, and two pieces of cannon.
This is his third unsuccessful attempt."

Kilmaine energetically and ably commanded troops involved in the Siege of Mantua for over 5 months.
 Wurmser finally surrendered on 3 February 1797.
 In a dispatch notifying the Minister of War about this important victory Kilmaine wrote:
"Kilmaine, General de Division and Commandant of Lombardy, to the Minister of War.
Milan, 17 Pluviose, 1797

Citizen Minister,

I avail myself of a courier which general Bonaparte sends from Romagna (in order to
announce to the Directory the defeat of the Papal troops), to acquaint you with the capture of Mantua, the news of which I received yesterday evening by a courier from Mantua itself I thought it necessary to announce this circumstance, because General Bonaparte, who is occupied in Romagna annihilating the troops of his Holiness, may probably have been ignorant of this fact when his courier departed.
Tho garrison are our prisoners of war, and are to be sent into Germany in order to be exchanged.
I have not yet received the articles of capitulation, but the commander-in-chief will not fail to send them by the first courier.

The capture of Mantua was celebrated in Paris by the firing of cannon and the erection of arches in honour of Bonaparte and Kilmaine 'the Irish Commandant of Lombardy', and a grand joy was diffused through every heart in the city on the fall of what they styled the Gibraltar of Italy, while Bonaparte, loaded with the diamonds of the vanquished corrupt Pope, and the spoils of our Lady of Loretto, pushed on to seek fresh conquests and new laurels.
 Kilmaine briefly remained in command in Mantua after its capitulation.
 Upon  returning to Paris, he was awarded the title Baron de Kilmaine.
