In May of 1794 the representatives of the people promoted him to chef de brigade. Two years later in 1796 Mainoni took command of the 44th of the Line and he joined the Army of the Rhine. He distinguished himself at Biberach that October and continued to serve with the Army of the Rhine through 1797.

In March of 1799 Mainoni joined Lecourbe's division and on the 16th he was beaten and taken prisoner at Schuls. Five months later he was exchanged for Austrian General Auffenberg. Mainoni immediately rejoined the army and in September he served under Soult at the crossing of the Linth during the Battle of Zürich .

In March of 1800 Mainoni joined the Army of the Reserve and he took command of the 28th of the Line as part of the advance guard under General Lannes.
