Naturally, our commanders tried to interrupt these works, and there were many skirmishes – sometimes four or five in a day. But the labour went on more or less continuously for several months until Caesar had completed a fifteen-mile fortified line that ran all the way round our position in a great loop, from the beaches to the north of our camp to the cliffs to the south. Within this loop we built our own system of trenches facing theirs, with perhaps fifty or a hundred paces of no man’s land between the two sides. Siege engines were brought up and the artillerymen would lob rocks and flaming missiles at one another. Raiding parties would creep across the lines at night and slit the throats of the men in the opposing trench. When the wind dropped, we could hear them talking. Often they shouted insults at us; our men yelled back. I remember a constant atmosphere of tension. It began to prey on one’s nerves.
Cicero fell ill with dysentery and spent most of his time reading and writing letters in his tent. ‘Tent’ was something of a misnomer. He and the leading senators seemed to vie with one another to see who could make their accommodation the most luxurious. There were carpets, couches, tables, statues and silverware shipped over from Italy on the inside, and walls of turf and leafy bowers outside. They dined with one another and bathed together as if they were still on the Palatine. Cicero became particularly close to Cato’s nephew Brutus, who had the tent next door, and who was seldom seen without a book of philosophy in his hand. They would spend hours sitting up talking late into the night. Cicero liked him for his noble nature and his learning but worried that his head was actually crammed too full of philosophy for him to make practical use of it: ‘I sometimes fear he may have been educated out of his wits.’
One of the peculiarities of this style of trench warfare was that one could also have quite friendly contact with the enemy. The ordinary soldiers would periodically meet in the unoccupied middle ground to talk or gamble, although our officers inflicted severe penalties for fraternisation. Letters were lobbed over from one side to the other. Cicero received several messages by sea from Rufus, who was in Rome, and even one from Dolabella, who was with Caesar less than five miles away, and who sent a courier under a flag of truce:
Cicero’s breast could barely contain all the conflicting emotions aroused by reading this extraordinary missive – delight that Tullia was well, outrage at his son-in-law’s impudence, guilty relief that Caesar’s policy of clemency still extended to him, fear that the letter could fall into the hands of a fanatic like Ahenobarbus who might use it to bring a charge of treason against him …
