Which dictator often struggled with a magister equitum named Minucius Rufus?

The correct answer highlights Quintus Fabius Maximus, known for his role as a Roman general and statesman during the Second Punic War. Fabius was given the title of dictator and famously employed a strategy of attrition against Hannibal, often avoiding direct confrontation.

The struggle with Minucius Rufus is a significant aspect of Fabius's military leadership, particularly because Minucius, who was appointed as his magister equitum (master of the cavalry), at times disagreed with Fabius's cautious tactics. This relationship depicts a critical moment in Roman military history, where differing strategies between leaders could lead to tension and conflict within the ranks. Ultimately, Fabius's strategy proved to be effective in the long term, showcasing his ability to adapt and lead despite the challenges posed by Minucius's more aggressive approach.

The other figures mentioned do not have a notable or direct link to Minucius Rufus in a way that defines their historical narrative. Their military contributions and challenges were significant in their own rights but did not involve the same dynamic seen between Fabius and Minucius.
