This is the
Bharat-Rakshak page on the Chachro raid from a contemporary newspaper:
This raid was undertaken by the 10 Para Commando Battallion under the command of Lt Col His Highness Sawai Bhawani Singh of Jaipur. The Unit was based at Sarupkatala, south west of Barmer town and on the outbreak of hostilities infilitrated across to Pakistani lines on the night of December 5th.....
Each force was mounted on Jonga 4X4 Jeeps heavily equipped with MMGs and packed with supplies.....The raiding party came under fire on reaching the outskirts of Chachro, but by daylight the Commandos neutralised all the threats and cleared the enemy from Chachro. 17 Prisoners and a huge number of small arms were captured. As the day progressed, C Group returned to base along with the Prisoners. A Group proceeded to raid the town of Virawah. The move was undertaken in broad daylight in the desert.
MOD
During the 1971 Indo-Pak war, the unit, then designated as ‘10 Para Commando’, carried out a daring 80 km-deep raid inside Pakistan’s territory
on the Indus Rangers HQ at Chachro (Sind). The battalion carried out many other vehicle-borne raids during the 1971 war.
For this unparalleled gallantry, the unit was
awarded Battle Honour Chachro and Theatre Honour Sind. For his courageous leadership, military acumen and foresightedness, the CO of this daredevil unit was awarded Maha Vir Chakra. In adition, the unit also earned two Vir Chakra, three Sena Medals and one Mention-in Despatches.
BTW a Google search on "10 Para", Chachro has these two links above, but the number one search result is of this BRF thread!
