Plutarch Eumenes 2

[1] However, Eumenes was often in collision with Alexander, and he got himself into danger through Hephaestion. In the first place, for instance, when Hephaestion assigned to Euius the flute-player the quarters which his servants had already taken up for Eumenes, Eumenes, accompanied by Mentor, came in a passion to Alexander and cried out that it was best for him to throw away his arms and be a flute-player or a tragic actor. The immediate result was that Alexander shared his indignation and heaped abuse upon Hephaestion.

[2] Soon, however, he changed his mind and was angry with Eumenes, feeling that he had indulged in insolence towards himself more than in bold words against Hephaestion.
  Again, when Alexander was sending out Nearchus with a fleet to explore the outer sea, he asked money of his friends, since the royal treasury was empty. Eumenes was asked for three hundred talents, but gave only a hundred, and said that even these had been slowly and with difficulty collected for him by his stewards. Alexander made no reproaches, nor did he take the money, but ordered his servants secretly to set fire to the tent of Eumenes, wishing to take its owner in a manifest lie when the treasure was carried out of it.

[3] But before that could be done the tent was consumed, and the destruction of his papers made Alexander repent him of his orders. Still, the gold and silver that was melted down by the fire was found to be more than a thousand talents’ worth. Alexander took none of it, however, but actually wrote to his satraps and generals everywhere to send copies of the documents that had been destroyed, and ordered Eumenes to take them all in charge.

[4]
  And still again, Eumenes had a quarrel with Hephaestion about a certain gift, and much abusive language passed between them. At the time, indeed, Eumenes was no less in favour than before; but a little while afterwards Hephaestion died, and the king, in his bitter sorrow, dealt harshly and was severe with all who, as he thought, had been jealous of his favourite while he lived and now rejoiced at his death. Eumenes, in particular, he suspected of such feelings, and often reproached him for his former quarrels with Hephaestion and his abusive language towards him.

[5] But Eumenes, who was wily and persuasive, tried to make what threatened his ruin conduce to his salvation. He sought refuge, namely, in Alexander’s ardent gratitude towards Hephaestion, suggesting honours which were most likely to adorn the memory of the deceased, and contributing money for the construction of his tomb lavishly and readily.
