  It is shown that bulk acceleration during reconnection of extremely strong
magnetic fields near compact objects can accelerate ions to Lorentz factors of
$\sim 10^2 \sigma^{3/5}$ under general conditions, where $\sigma$, the magnetic
energy per current-carrying proton rest energy, can approach $10^{15}$. For
magnetar-type fields, neutrons and neutrinos can be generated at potentially
detectable levels via hadron polarization. Ultrahigh energy photons can also be
emitted and escorted from the high field region by Poynting flux.
