  A model is presented which demonstrates that the attosecond pulse structure of an HHG seed may be retained through to saturation in an FEL amplifier. At wavelengths of ~12nm, a train of attosecond pulses of widths ~300 attoseconds with peak powers in excess of 1GW are predicted from full 3D simulation. Methods for improving these results are discussed.
