The Telescope Array (TA) is the largest cosmic ray detector in the Northern hemisphere. Initially designed to study ultra high energy cosmic rays of energies above $10^{18}$ eV. The Telescope Array Low-energy Extension (TALE) extends the sensitivity of TA down to $10^{15.6}$ eV. The original TA consists of three fluorescence detectors, viewing 3$^{\circ}$ to 31$^{\circ}$ in elevation each, and overlooking an array of scintillation counters. TALE adds additional fluorescence telescopes at the TA Middle Drum (MD) fluorescence detector site, and overlooking a graded infill array of counters. Together, TALE and MD see a combined sky coverage of 114$^{\circ}$ in azimuth and 3-59$^{\circ}$ in elevation. In this work, we present a first measurement of the energy spectrum made by the combined TALE and MD fluorescence detectors operating in monocular mode.
