Last night I introduced the Zeppelin Staaken and the H-P 0/400s to our group.
We did two scenarios, the first was April, 1918. Two H-P 0/400s where out bound to bomb a German rail station, escorted by a pair of SPAD XIIIs. Flying against them where three Albatros D,Va's and one Pfalz D.III. The HP's stayed close together for mutual support, and actually survived the flight.
The second scenario had two Staaken's with no support, but again, staying in close formation. Facing them three Camels and two SPAD XIIIs.
One Staaken was destroyed, and the other damaged, while three of the attacking planes where shot down.
