 On the morning of 27 June , Prpić launched a three @-@ <unk> assault to clear the routes to Nevesinje . Prohaska commanded the push east along the Mostar – Nevesinje road by a force close to two battalions , Francetić led his unit of Ustaše north from Berkovići through the mountains via Odžak to approach Nevesinje from the south , and two companies of the 11th Battalion thrust southwest along the road from Plužine . Once this task was complete , the NDH forces were to vigorously pursue the rebels and destroy them .
