We are firing with four machine guns and at least eighty carbines from secure, covered positions into the advancing horde. Our machine gun bursts rip openings in their ranks. Dead and wounded are hitting the ground all the time. But more of them are coming through the haze, and we can’t see them clearly. The first ones are now so close to our positions that we can readily make out the plump, bent figures with rifles and Russian Kalashnikovs.
