Adrestus and Amphius, the sons of Merops

Oswald  Memorial  p. 40

Also Adrestus and Amphius
Everyone knew they were going to die
They were the sons of Merops the prophet
He begged them to stay at home but they couldn't listen
Their own ghosts were calling them to Troy
Immaculate in clean linenThey set out together but Death
was already walking to meet them 

Like a goatherd stands on a rock
And sees a cloud blowing towards him
A black block of rain coming closer over the sea
Pushing a ripple of wind inland
He shivers and drives his flocks into a cave for shelter

A couple of interesting things going on here.  The "immaculate in white linen" line is a loose translation of "λινοθώρηξ", but has connotations of "walking to Troy in their shrouds", as in the cowboy in Streets of Laredo, "wrapped up in white linen and cold as the grave".  They are walking to their deaths and this is already known; they're dead men walking. Oswald gets the names from the Catalog of Ships; the rest of the lines are repeated in book 11.

The "goatherd" simile comes from Book 4 after the Paris/Menelaus incident. Agamemnon has just accused a bunch of Greeks of being like stunned fawns, and now moves on to where the two Aiantes are marshalling a bunch of boys who are dark and foreboding like a storm cloud about to bring a storm.  Here the storm cloud seen by the goatherd is the cloud Merops saw over his son's lives, the black Keres already leading them; this is the cloud that will engulf his sons, like stunned fawns,  in book 11. (Okay, they aren't actually described as stunned fawns.) Later a dozen Trojan boys "like stunned fawns" will be led out of the river by Achilles and bound to be sacrificed on Patroclus' funeral pyre.
