Aeneas and the Trojans leave Carthage (Roman d'Aeneas, Bnf Fr784, f70r)

This is the very beginning of the Roman d'Enéas :

Quant Menelaus ot Troie assise :
Ains n'enturna qu'il l'ot p[ri]se,
Gasta la terre & tot le regne
Pour la venja[n]-ce de sa fame

(When Menelaus had laid siege to Troy, he moved no more until he had taken it, he devastated whole country and kingdom to avenge the outrage inflicted through his wife.)

The miniature and historiated letter represent episodes that come later: the Trojans' flight after the capture of Troy, then Dido's suicide.

Eneas cherca le rivaige,
found y a .XX. de lor barge,
il entra enz a tout sa gent,
et bint et eve et forment
trouva es nez a grant plenté.
Du rivaige sont esquipé (v. 68-72)

Contrary to the narrative of the Aeneid, which imagines the Trojans fleeing to the forests of Phrygia where they build their own boats, the Roman of Aeneas embarks the Trojans directly from Troy, on boats stolen from the Greeks.

As for Dido's suicide:

She holds the espee all naked,
Under the breast she has ferue.
O tout le cop saut enz el ré
Que sa serror ot apresté (v. 2116-9)

(She brandishes the naked sword and strikes herself under the breast. At the same time she rushes to the pyre her sister had prepared.)
