Solving Time: 33 minutes

Not very difficult if you're up on your arcana. The N.E. corner contributed most to my time. I have Charles Lamb's pen name tattooed inside my eyelids, but found it has been obscured by a list of Hebridean islands. I had also forgotten the miscellaneous ana and couldn't see how archetype worked. I hope the golfing reference atones for the literary allusions. And so, without further ado...

Across
1	WITCH-HUNT sounds like "Which Hunt?". Holman Hunt was the Pre-Raph who painted "The Scapegoat", Leigh Hunt the writer and poet, famed for playing shuttlecock in prison. I'm not convinced it works, but it would be ungenerous to carp.
6	I think I can omit this one without causing too much of it.
9	DRILLED, a double definition. Tommy being Tommy Atkins
10	C for chapter beside ELIA (the pseudonym of Charles Lamb) holding E.G., for say = ELEGIAC, like an elegy, or, for the classical prosodists amongst us [de]noting a distich or couplet the first line of which is a dactylic hexameter and the second a pentameter, or a verse differing from the hexameter by suppression of the arsis or metrically unaccented part of the third and the sixth foot. Charles Lamb, "the most lovable figure in English literature", was in Leigh Hunt's circle and brother of Mary, who killed her mother with a kitchen knife. It's a long story.
11	ERNST = onE superioR iN hiS arT, &lit. Nicely done. Max Ernst was a seminal Dadaist, Surrealist and Expressionist, one-time husband of Peggy Guggenheim.
12	REHYDRATE = (DRY EARTH)* around E
13	ADIEU Is that a double definition? Nancy and Nice both being French cities, of course.
14	(HANDY CURE) = HUE AND CRY
17	TOMAHAWKS = TOMS employed as entrapment device for A HAWK. That would be the missiles rather than the small axe, although see Mary Lamb, op. cit.
18	BEIGE = BEE around G.I. reversed.
19	KNOTGRASS sounds like "not grass"
22	LAWFUL = AWFUL
24	OSTRICH would be MOST RICH if placed after M for mile.
25	(SEEK LAD)* = ESKDALE, the only river valley in the Lake District not to have any lakes. When solving I naturally assumed it was the former parish of Eskdale in N.E. Cumbria.
26	A, for leading character, in K. NED for King Edward = KNEAD. As in one, two, three Neds, Richard two.
27	R for run + NOSE reversed + A + N for new + C.E. for church = RESONANCE

Down
1	Deliberately omitted. I hope this won't alienate me from our golfing contributors.
2	TRI ENNI sounds like "try any" + UM for hesitation = TRIENNIUM. A partial homophone, no less. I'm still recovering from Friday's pinkos.
3	HALT for stop cradles F for following + RUTH for girl = HALF-TRUTH
4	UNDER THE WEATHER = THE (the second the) thrown into UNDER THE WEAR, for "on river bed". The Wear is challenging the Dee for the title of crosswords' most cited river. I'm awaiting the rise of the Todd.
5	THE THREE SISTERS, both a Chekhov play and the Weirds from Macbeth. Not to be confused with the rock formation.
6	DREAD = D for duke, has bREAD
7	ANITA = IT for Italian in ANA, which crops up from time to time in crosswords, being literary miscellanea or anecdotes.
8	ARCHETYPE = ARCH(i)E + TYPE for "produce copy"
13	ANTIKNOCK = (IN TANK)* + OK around C for cold
15	NEBRASKAN = BEN reversed + RAN around ASK
16	(IF HE CANT I)* = CHIEFTAIN
20	OUTRE, being hidden in withOUT REsistance
21	L for Liberal inside GUID = GUILD.
23	LIEGE, double definition, a city in Belgium and something to do with Lords.
