"Sorry to pull you back from rest, Colonel," said the Brigadier, when the commander of the Hairy Jocks reported; "but the Divisional General considers that the only feasible way to hunt the Boche from the Kidney Bean is to bomb him out of it. That means trench-fighting, pure and simple. I have called you up because you fellows know the ins and outs of the Kidney Bean as no one else does. The Brigade who are in the line just now are quite new to the place. Here is an aeroplane photograph of the Redoubt, as at present constituted. Tell off your own bombing parties; make your own dispositions; send me a copy of your provisional orders; and I will fit my plan in with yours. The Corps Commander has promised to back you with every gun, trench-mortar, culverin, and arquebus in his possession." In due course Battalion Orders were issued and approved. They dealt with operations most barbarous amid localities of the most homelike sound. Number Nine Platoon, for instance (Commander Lieutenant Cockerell), were to proceed in single file, carrying so many grenades per man, up Charing Cross Road, until stopped by the barrier which the enemy were understood to have erected in Trafalgar Square, where a bombing-post and at least one machine-gun would probably be encountered. At this point they were to wait until Trafalgar Square had been suitably dealt with by a trench-mortar. (Here followed a paragraph addressed exclusively to the Trench-Mortar Officer.) After this the bombers of Number Three Platoon would bomb their way across the Square and up the Strand. Another party would clear Northumberland Avenue, while a Lewis gun raked Whitehall. And so on. Every detail was thought out, down to the composition of the parties which were to "clean up" afterwards--that is, extract the reluctant Boche from various underground fastnesses well known to the extractors. The whole enterprise was then thoroughly rehearsed in some dummy trenches behind the line, until every one knew his exact part. Such is modern warfare. Next day the Kidney Bean Redoubt was in British hands again. The Hun--what was left of him after an intensive bombardment of twenty-four hours--had betaken himself back over the ridge, _via_ the remnants of his two new communication trenches, to his original front line. The two communication trenches themselves were blocked and sandbagged, and were being heavily supervised by a pair of British machine-guns. Fighting in the Redoubt itself had almost ceased, though a humorous sergeant, followed by acolytes bearing bombs, was still "combing out" certain residential districts in the centre of the maze. Ever and anon he would stoop down at the entrance of some deep dug-out, and bawl-- "Ony mair doon there? Come away, Fritz! I'll gie ye five seconds. Yin, Twa, Three--"
