The historicity of the Sacred Band is largely accepted by historians; it is detailed in the writings of numerous classical authors, especially Plutarch. Noted classical historians such as John Kinloch Anderson and George Cawkwell accept Plutarch's "Life of Pelopidas", which contains the most detailed account of the Sacred Band, as a highly reliable account of the events, in contrast to Xenophon's patchy treatment of Theban history. Other noted classical scholars like Frank William Walbank and Felix Jacoby have also defended Callisthenes' descriptions of land battles in the past. Walbank commented that his depictions of the Battle of the Eurymedon, Gaugamela, and Tegyra (all surviving through Plutarch) are quite adequate. While Jacoby, responding to claims that Callisthenes was unreliable in accounts of land battles in contrast to Xenophon, pointed out that Callisthenes did accurately describe the details on the Battle of Tegyra. He summarized his opinion of Callisthenes' account with ""Sie ist panegyrisch gehalten, aber sachlich nicht unrichtig." is panegyrical, but it is not factually incorrect." This is echoed by the historians John Buckler and Hans Beck who conclude that "In sum, Plutarch's description of the battle of Tegyra does justice both to the terrain of Polygyra and to the information gleaned from his fourth-century sources. There is nothing implausible or unusual in Plutarch's account, and every reason to consider it one of the best of his battle pieces." They also had the same opinion of his account on Leuctra, dismissing assertions that his accounts were confused or rhetorical.
