Taupin transferred again to Spain where he fought in the Peninsular War including the battles of Bussaco and Salamanca.

On 18 September 1791, he joined the 1st battalion of National Volunteers of the Oise as a sous lieutenant and was named captain on 31 January 1792.

[8] When the division was attacked by an overwhelmingly superior force of Russians and Austrians on 11 November, it was able to cut its way out of the trap, though it suffered losses of 2,300 men.

[7] The 1st, 2nd, and 3rd Battalions of Taupin's 103rd Regiment served in Gazan's 2nd Division of Lannes' V Corps at the Battle of Jena on 14 October 1806.

[11] The V Corps missed the bloody Battle of Eylau because it and Nicolas Léonard Beker's dragoon division were covering Warsaw.

[12] The corps was under the command of Anne Jean Marie René Savary when it fought in the Battle of Ostrołęka on 15 February.

[5] The War of the Fifth Coalition found him in command of a brigade in Marshal François Christophe de Kellermann's Reserve Corps, a rear-echelon formation based at Frankfurt.

[15] On 8 July 1809 the brigades of Taupin and Lameth with some attached units were defeated by Michael von Kienmayer's Austrians in the Battle of Gefrees.

[17] On 15 September 1810, he commanded a brigade in Bertrand Clausel's division of Junot's VIII Corps during the Battle of Bussaco.

[20] Taupin led a brigade in Julien Augustin Joseph Mermet's division at the Battle of Fuentes de Oñoro on 3–5 May 1811.

The brigade comprised the 1st, 2nd and 4th Battalions of the 50th and 59th Line Infantry Regiments and was part of Louis Henri Loison's VI Corps.

[23] In the summer of 1812, Taupin called his officers together at a village church and lectured from the pulpit about the overuse of horses and mules in the infantry.

[24] At the Battle of Salamanca in July 1812, Taupin led a brigade in Antoine Francois Brenier de Montmorand's 6th Division.

Attacked by Le Marchant's horsemen, Brenier's other brigade, consisting of the 22nd Line, shot down one-fourth of the troopers of the leading squadron.

[27] In the Burgos Campaign during October 1812, Taupin commanded the 3rd Division of the Army of Portugal which was formerly led by Claude François Ferey.

[31] In mid-May, while Clausel attacked the guerillas under Francisco Espoz y Mina with three divisions, Taupin's troops guarded Navarre.

[34] Though pursued for a time by Wellington's troops, Clausel retreated via Jaca over the Somport Pass on 12 July.

[37] In the Battle of the Pyrenees in late July 1813, Taupin's division fought in Clausel's corps and suffered 131 killed, 1,045 wounded and 26 captured.

[40] In the Battle of San Marcial on 31 August, Clausel's divisions crossed the Bidassoa River at dawn, covered by fog.

Vandermaesen marched upstream to the bridge at Bera (Vera) and at 2:00 am on 1 September began making desperate attacks against the 100 British riflemen defending the span.

Lecamus' brigade (under Colonel Cambriel) defended the Hog's Back and the Vera Pass on the left flank.

[43] Allied forces led by James Kempt drove back Cambriel's brigade rather easily and seized the crest while sustaining only 78 casualties.

The battalion of the 88th Line in the Signals Redoubt repulsed several attacks by the British 52nd Foot but it was soon isolated by the retreat of other units.

[51] Though the Battle of the Nive lasted from 9 to 13 December 1813, Taupin's division was only lightly engaged, sustaining only 197 casualties.

[52] The 4th Division was involved in the advance on Arcangues on 10 December, but the Allied position was so strong that Clausel declined to press the attack.

[53] At the Battle of Orthez on 26 February 1814, Taupin's division held the French right flank at the Plassotte Knoll overlooking the village and church of Saint-Boès.

Despite being reinforced by the Portuguese 1st Caçadores from the Light Division, Cole's entire line soon collapsed and his soldiers abandoned Saint-Boès.

After a four-hour defense, Taupin's tired men withdrew; they were the last French soldiers to relinquish their position.

The route being through muddy fields, Beresford's march was considerably delayed, causing the Spanish corps to attack prematurely and suffer a repulse.

Soult ordered Taupin's division to change position and then charge downhill against the Allied forces.
