Fight or Flight, Road to No Man’s Land, and Chuck Dixon’s run on this book all come to an end in Detective 729 (Feb. 99).
Gordon and Sarah return to Gotham, and he finds a core of the police force also willing to defy the government and stay on their posts. Bullock, Montoya, Bock and Kitch are all there.
As the military close the bridges, a hooded man leads a crowd of stragglers, demanding to be let out of the city.
Despite Robin and Nightwing’s efforts, Mr. Scratch’s men blow the bridge.
They do rescue the hooded man, revealed to be Simpson Flanders, who has certainly seen better days.
Mr. Scratch’s plans come to an abrupt halt, when the Joker single-handedly wipes out his men. He has no interest in any newbies claiming Gotham.
Nightwing and Robin discover Wayne Manor gone, plowed into the cave. The Return of Bruce Wayne storyline, much more recently, would amend this, that only one wing of the manor was destroyed at this point. But that clearly goes against what is shown here, so I view that as being the result of Superboy punching a wall.
Don’t get the reference? Stick around, I’ll get to it one day.
