We present high angular and spectral resolution H I 21 cm line observations toward the cometary-shaped compact H II region G213.880-11.837 in the GGD 14 complex. The kinematics and morphology of the photodissociated region, traced by the H I line emission, reveal that the neutral gas is part of an expanding flow. The kinematics of the H I gas along the major axis of G213.880-11.837 shows that the emission is very extended toward the SE direction, reaching local standard of rest (LSR) radial velocities in the tail of about 14 km s{sup -1}. The ambient LSR radial velocity of the molecular gas is 11.5 km s{sup -1}, which suggests a champagne flow of the H I gas. This is the second (after G111.61+0.37) cometary H II/H I region known.
