During a cavalry charge, Sir Philip Sidney was fatally wounded, as it turned out, because the surgeons could not remove the musket ball from his thigh and he died of gangrene poisoning in the city Arnhem on October 17, 1586. Biographers now, like Alan Stewart, dismiss the legend that Sidney removed a piece of his body armor that would have protected him from this wound because another Englishman did not wear it. Stewart comments that the English generally preferred light armor, so Sidney wouldn't have been wearing it in the first place.
His body was returned to England and he was buried in the Old St. Paul's Cathedral but his grave and monument were destroyed in the Great Fire of London in 1666. His posthumous reputation as a Renaissance courtier was aided by his biographer Fulke Greville and Edmund Spenser's elegy Astrophel.
The Poetry Foundation notes in its biography of Sidney that he met Edmund Campion in 1577 during his "official mission of extending the queen's condolences to the family of Maximilian II":
