MARCUS    (Antonius brother) coming out of Italy, had passed the sea, 
BRUTUS    and came with great speede towards the citie of Dyrrachium, 
    and Apollonia, to get the souldiers into his hands, which 
    Gabinius had there. Brutus therefore to prevent him, went 
    presently with a fewe of his men in the middest of winter 
    when it snewe hard, and tooke his way thorough hard and 
    fowle contries, and made such speede in deede, that he was 
    there long before Antonius sumpters, that caried the vittells.

    places. Brutus being very faynt, and having nothing in his

    enemies, and comming to the gates of the citie, they prayed 
    the warders to help them to bread. When they heard in 
    what case Brutus was, they brought him both meate and 
Brutus thank-    drinke: in requitall whereof, afterwards when he wanne the

    sakes. Now, when Caius Antonius was arrived in the citie

    unto him. But when he understoode that they went all to 
    Brutus, and furthermore, that the Citizens of Apollonia did
