Guillaume Dode de la Brunerie, Viscount of Martignac (April 30, 1775 – February 28, 1851) was a Marshal of France.

Promoted to major in 1801, Dode stayed in Egypt until the French forces there capitulated, only returning to France in November 1801.

Dode was with Lannes and Joachim Murat when they famously captured a bridge over the Danube by bluffing the Austrian commander Auersperg into believing a cease fire had been signed.

However, for the campaign of 1806, Dode was again made head of the engineers on Lannes' staff, a function which saw his participation in the battles of Saalfeld and Jena.

In 1812, Dode de la Brunerie was made head of the engineers in the III Corps under Marshal Ney.

When Napoléon returned from Elba, Dode de la Brunerie served as commandant of engineers under the Bourbon army opposing the emperor.

Napoleon wanted to confirm him in his positions but Dode de la Brunerie refused to be employed during the Hundred Days as he had given his oath of loyalty to Louis XVIII.

When the July Revolution broke out and Charles X abdicated, the new king Louis-Philippe retained Dode de la Brunerie in all his functions.

The construction of the Parisian fortification took seven years to complete and cost approximately 140 million francs and gave Dode de la Brunerie the nickname of being the Vauban of Modern Times.

When the Revolution of 1848 erupted, Dode de la Brunerie decided to retire to private life.
