A more than usual number of persons assembled yesterday, in the expectation of seeing something grand, a rumour having got abroad that it was the intention of the GENERAL to call out the Brook Green Militia (which distinguished corps, in consequence of the recent augmentation, now numbers nearly two file and a half), and to brigade them with the Queen's Piebalds. It was said, too, that the forces thus brought together would be separated as two divisions, and occupy respectively the Scrubs and Starch Green, and that a sham fight would take place. But the idea (if ever entertained) was abandoned--for what reason we cannot say, as we do not happen to know--these things being kept in profound mystery: but we are informed that a sergeant is under arrest, and will probably be "smashed" for having said that the ground on Starch Green was too stiff for the Piebalds. Such an atrocious attempt at a joke will meet with little sympathy from our readers, and we doubt not the offender will meet with his deserts, though, after all, perhaps, the idea _was_ given up on that ground. The Piebalds, having sole possession of the Scrubs, went through their evolutions with their accustomed precision. The "brilliancy" of the movements was somewhat abated in consequence of GENERAL PUNCH having ordered "field exercise" instead of "marching order." But those who have any regard for our gallant defenders will, we are sure, willingly give up "glittering helmets," &c., for anything that may conduce to their comfort. We subjoin a letter which has come into our hands, which will show that the privates are subjected to privations and moving accidents in peace as well as war--in barracks as well as in the field:-- _To_ LIEUTENANT WHIFFIN, _Royal South-South-East-Middlesex Dun Browns_. "DEAR WHIFFIN,--I must tell you how we have been going on. Old PUNCH has been working us up in fine style--four field days a week, and riding drill on the off days; besides practising pitching tent in the afternoon in the barrack yard. However, he is such a jolly old fellow, that we don't mind a little extra work for him. One thing he has done which we are particularly thankful for. He lets us go to his reviews in field exercise instead of marching order. "Young GREEN of ours says he considers it a personal favour. You know he swapped helmets with CAPTAIN WIDEAWAKE when he (WIDEAWAKE) went up to the DUKE'S funeral, and has never been able to get his own back since. WIDEAWAKE is always 'so busy he can't give it him now.' The consequence is, that W.'s helmet rolls about on GREEN'S head like 'anything,' especially at a trot, and the scales are so long that he's obliged to keep his mouth open all the field day to keep it on his head. So that it's fortunate for him that he's only been a serrefile as yet. If he were to lead a troop he would have some difficulty in giving the word of command. Some recruits only recently dismissed have a similar difficulty to brave.
