Just off the wall, I fancy these ones:
*   Minoan athletes vaulting over charging bulls; suitably half-clad spectators
*   sarcophagus carver, or group of NKE morticians laying a mummy to rest
*   NKE dancers and musicians; diners watching the show
*   Assyrian queen in litter, with attendants
*   Scythian burial tumulus
*   Persian traitor being executed by "the boats"
*   ex-Socrates, with weeping disciples
*   Alexander killing Cleitus
*   Punic deity and firepit, with offering
*   Roman decimation
*   Sarmatian damsel proudly showing trophy to in-laws-to-be
*   shieldmaiden returning to camp with treasure chest under one arm, pretty boy over opposite shoulder
*   William the Bastard eating sand
*   laundry on line, washtub to one side
*   Timur playing chess
*   French irregulars plundering Henry V's baggage
*   Byzantine clergy and commanders kneeling at altar with icon
*   Michelangelo halfway through David
*   Landsknechts playing cards on drumhead
*   Mexican gladitorial sacrifice
*   Chinese gong; large man bashing it
*   Turkish slave market
*   Mamluk Arabian Nights harem
*   Cossacks writing insulting letter to Sultan
*   the incident behind the Mannequin Pis in Brussels
*   Swedish/NMA clergyman preaching to bare-headed soldiers
*   Cavalier roaring boy at table, bottle in hand, wench on knee
*   18th-century harpsichordist and flautist
*   18th-century malefactor running the gauntlet
*   18th-century duelists  (guess what my favourite movie is?)
*   Victorian civilians picnicking (also suit Russian ladies watching the battle of the Alma)

   Ideas?

Think you hit most of them there !

I've missed the point of the laundry

Picnickers could also be watching 1^st Bull Run, fleeing carriages optional

Washerwomen are very often mentioned in camps.

Oh, yes, Mother Courage and the Brechtian ensemble.
*   malefactor in stocks, possibly being teased by ragged kids

I'm up for those

Our hobby is reenacting mass murder! We all need straightjackets.

But I've got a certificate to prove my sanity

"I'm not crazy, my mother had me tested" (Sheldon Cooper, The Big Bang Theory).

Baggage Train.  Military.  n.  A train of vehicles, used to carry baggage, especially following an army.

Some components of a baggage train, the ammunition waggons, ration waggons, pontoon waggons, engineer waggons, mobile forges etc would be useful first.

Awww, you're no fun any more.

QuoteOur hobby is reenacting mass murder! We all need straightjackets.

Murder is the unlawful killing of another human.
Warfare generally moves the act of killing outside normal criminal law considerations (not always) and so please undo these straightjackets at once!

(mass killing; probably - no mens rea of the crime of murder however )
