Final answer:
The provided texts do not give information about a specific Heathobard prince whose death enabled the Danes to capture them. Instead, they cover various historical figures and events relevant to the Viking era and the early history of Denmark.
Step-by-step explanation:
The information provided does not specify a particular Heathobard prince whose death allowed the Danes to capture them, and the given texts do not contain details that directly answer this question. The texts do touch on historical and legendary figures and events such as Leif Erikson's voyages, the Christianization of the Danes, and events related to the colonization of Greenland and Vinland. The Jelling Stones, which represent the Christianization of Denmark with inscriptions and imagery of Christ, stand as Denmark's baptismal certificate and signify the nation-state's creation with the earliest use of the name Danmark. However, they do not provide information about the Heathobard prince in question.
