Bhagavad Gita

ದ್ರುಪದೋ ದ್ರೌಪದೇಯಾಶ್ಚ ಸರ್ವಶಃ ಪೃಥಿವೀಪತೇ ।
ಸೌಭದ್ರಶ್ಚ ಮಹಾಬಾಹುಃ ಶಂಖಾನ್ ದಧ್ಮುಃ ಪೃಥಕ್ ಪೃಥಕ್ ॥೧೮॥
drupado draupadeyāśca sarvaśaḥ pṛthivīpate |
saubhadraśca mahābāhuḥ śaṃkhān dadhmuḥ pṛthak pṛthak ||18||

Sloka 1:18
Gist of the sloka:
O King, the following then blew their conch one after another – Dhrupada, Sons of Draupadi and the great warrior Abhimanyu.
If one notices clearly, the conch was sounded off from Pandavas side in a systematic, hierarchical order of their positions. There was no confusions or noise being made for its own sake. The discipline showed how a small but well organized and determined army can have an impact on even numerical stronger but barely disciplined army. It also showed the high level of belief, determination and confidence that Pandavas had.
This was in strong contrast to the order and confusions in Kauravas’s army. There is another unique aspect. The number of people from Pandavas who sounded their conch was 18. Numerology as per Sanathana Dharma indicates 18 as the number for victory, Lord and final achievement. Mahabharatha is also known as Jaya. Ja means 8 and Ya means 1. Jaya =18 means Victory. This is as per Sanskrit alphabetical order.
In a strange coincidence, after the Pandavas 18 conch sounds the 18th para of Gita concludes.
