Bibulus then blockaded all the harbors along the coast, hoping to prevent any further crossings from Italy, and leaving Caesar stranded in Epirus. He found that he could not resupply his ships without abandoning the blockade, and so he attempted to bluff Caesar's legates at Oricum into persuading Caesar to agree to a temporary truce so that he could resupply. When Bibulus refused to guarantee the safety of the envoys Caesar wished to send to discuss a peaceful settlement with Pompey, Caesar realised it was a ploy and pulled out of negotiations. Determined to continue with the blockade, Bibulus pushed himself too hard; he fell ill in early 48 BC and died near Corcyra before the end of winter.
