All of them

At the entrance were stationed all the princes possessed of solar effulgence.

1. All of them had taken oaths (about standing by one another). 
2. All of them had standards decked with gold. 
3. All of them were attired in red robes, and all had red ornaments. 
4. All of them had red banners and all were adorned with garlands of gold, smeared with sandal-paste and other perfumed unguents; they were decked with floral wreaths.  

Firm bowmen, all they numbered ten thousand. Placing thy handsome grandson, Lakshmana, at their head, all of them, 

1. sympathising with one another in joy and grief, and 
2. emulating one another in feats of courage, 
3. desiring to excel one another, and 
4. devoted to one another's good, they advanced to battle.

Duryodhana, O monarch, was stationed in the midst of his forces. And the king was surrounded by the mighty car-warriors, 

1. Karna, 
2. Duhsasana, and 
3. Kripa, and had a white umbrella held over his head. And fanned with yak tails, he looked resplendent like the chief of the celestials. 

And at the head of that army was the commander Drona looking like the rising sun. And there stood the ruler of the Sindhus, of great beauty of person, and immovable like the cliff of Meru. Standing by the side of the ruler of the Sindhus and headed by Aswatthaman, were, O king, thy thirty sons, resembling the very gods. 

There also on Jayadratha's flank, were those mighty car-warriors, viz., the ruler of Gandhara, i.e., the 

1. gamester (Sakuni), and 
2. Salya, and 
3. Bhurisrava.
