Andy Smith, the wee Scot from Ayrshire who manages Sugar Ray Leonard's next opponent, is suggesting that security may be increased around the White House to prevent a repetition of the 1814 sacking by the British.

"We're going to get even for what you bloody Yanks did to us at Yorktown," Smith said of the revival of boxing excellence in the British Isles, where the sport was born.

"Dave Green is going after Leonard's championship on the 31st of March, because Prime Minister Margaret Thatcher instructed us to collect all the titles we can in the colonies."

Alan Minter of Crawley, England, became the only undisputed title-holder in the world on Sunday taking the middleweight championship away from Vito Antuofermo in Las Vegas.

Before the fortnight is over the British could shock the international scene if Green upsets Leonard for the World Boxing Council welterweight title at Capital Centre, and Liverpool native John Conteh takes the WBC light heavyweight championship from Matthew Saad Muhammad on March 29 at Atlantic City.

That would make five titles for Britian, since Maurice Hope of Hackney owned the WBC junior middleweight championship and James Watt of Glasgow, Scotland, the WBC light-weight crown before Minter's success on Sunday.

Presently, the United States holds four WBC titles and three World Boxing Association versions; Mexico three titles; Puerto Rico, Panama, Colombia and Korea two each, and Nicaragua and Uganda one each.

Manager Smith acknowledged that Britons have been suffering poor jokes about their slump in the manly art of self defense since the days of "Phaintin' Phil" Scott, whose mostly horizontal career spanned 1919-1931.

His reputation for frequent trips to the canvas was so international that during one of the low points of boxing in this country, Washington promoter Vince McMahon was asked if the sport were dying.

"If Phil Scott couldn't kill boxing, nothing will," McMahon predicted with admirable foresight.

Green's manager says of the rise of the Union Jack, "Our boxers are restoring the roar to the British lion for the first time since Winston Churchill. And this isn't a lend-lease program; we intend to keep these titles."

In his clipped East Anglia accent, Green, a root farmer in Cambridgeshire who grows potatoes, carrots, turnips, and beets said, "Training here in Knoxville, Tenn., I got homesick on Monday. It was misty and cold, like London. But it will be different in Washington; a couple of jumbo jet loads of fans are coming over, including my mother, father, and brother."

"War" correspondents from Britain already are on the trail, having begun the campaign on Sunday in Las Vegas.

A few will visit Green's training quarters, which he shares with John Tate in Knoxville. Most of the journalists will be here when Green arrives on the weekend to finish training and will go to Atlantic City for the Conteh-Muhammad bout and return for Green-Leonard.

"I think I have a tougher task than Conteh," Green said. "Leonard is supposed to be the best fighter around now, pound for pound. But he has had only 26 bouts (all winning ones) and I have scored that many knockouts. I don't think he has ever really been hit."

Green, 26, has won 33 of 35 bouts, losing on knockouts to Carlos Palomino, former WBC champion, because of a cut eye, and to Jorgen Hansen of Denmark, counted out.

Leonard and Green have fought three common opponents -- Andy Price, Rafael Rodriguez, and Dick Ecklund. Leonard decisioned Rodriquez and Ecklund, and knocked out Price in the first round. Green decisioned Price and Ecklund and knocked out Rodriguez.
