Piran Parts from His Brothers

From C3.27, Piran Exhorts His Champions. It illustrates C3.27.35–45:

C3.27.35
To Farshidvard and Lahhak Piran spoke:“Great chiefs, guard Turan from the coming stroke.
C3.27.36
The safety of the army on this fieldMust be your care; stand firm, its living shield.
C3.27.37
Set there a watchman on the mountain height,To scan the field while day affords him light.
C3.27.38
There let him keep his vigil through the night,And count the stars until the dawn grows bright.
C3.27.39
If ill should come from heaven’s turning sky,And all its favor wholly pass us by,
C3.27.40
Then hurry back to Turan; let your flightBe swift as smoke when fortune turns to spite.
C3.27.41
No others of our house are left to stand;Time felled our mighty warriors with its hand.
C3.27.42
What can I teach of time and all its ways?Time is itself the teacher of our days.”
C3.27.43
They clasped each other, weeping in their pain,Then turned away, their bitter tears like rain.
C3.27.44
They parted from the ranks with cries of grief,And loud lament accompanied each chief.
C3.27.45
Then Piran, filled with vengeance, rode back out,And reached the field with his loud battle-shout.
