Pompey did not immediately follow up on his success. An indecisive winter (49–48 BC) of blockade and siege followed. Pompey eventually pushed Caesar into Thessaly and, urged on by his senatorial allies, he confronted Caesar near Pharsalus. Pompey's allies disagreed with Pompey over whether to fight at Pharsalus. Pompey, who wanted to starve Caesar's soldiers, had his hand forced by his allies.
