Fifty-three years ago, when newly elected Dwight Eisenhower moved into the White House, America's southern frontier was as porous as a spaghetti sieve. As many as 3 million illegal migrants had walked and waded northward over a period of several years for jobs in California, Arizona, Texas, and points beyond. President Eisenhower cut off this illegal traffic. He did it quickly and decisively with only 1,075 United States Border Patrol agents – less than one-tenth of today's force. The operation is still highly praised among veterans of the Border Patrol.

Although there is little to no record of this operation in Ike's official papers, one piece of historic evidence indicates how he felt. In 1951, Ike wrote a letter to Sen. William Fulbright (D) of Arkansas. The senator had just proposed that a special commission be created by Congress to examine unethical conduct by government officials who accepted gifts and favors in exchange for special treatment of private individuals. General Eisenhower, who was gearing up for his run for the presidency, said "Amen" to Senator Fulbright's proposal.

He then quoted a report in The New York Times, highlighting one paragraph that said: "The rise in illegal border-crossing by Mexican 'wetbacks' to a current rate of more than 1,000,000 cases a year has been accompanied by a curious relaxation in ethical standards extending all the way from the farmer-exploiters of this contraband labor to the highest levels of the Federal Government." Years

 later, the late Herbert Brownell Jr., Eisenhower's first attorney general, said in an interview with this writer that the president had a sense of urgency about illegal immigration when he took office. America "was faced with a breakdown in law enforcement on a very large scale," Mr. Brownell said. "When I say large scale, I mean hundreds of thousands were coming in from Mexico [every year] without restraint." Although an on-and-off guest-worker program for Mexicans was operating at the time, farmers and ranchers in the Southwest had become dependent on an additional low-cost, docile, illegal labor force of up to 3 million, mostly Mexican, laborers. According to the Handbook of Texas Online, published by the University of Texas at Austin and the Texas State Historical Association, this illegal workforce had a severe impact on the wages of ordinary working Americans. The Handbook Online reports that a study by the President's Commission on Migratory Labor in Texas in 1950 found that cotton growers in the Rio Grande Valley, where most illegal aliens in Texas worked, paid wages that 

were "approximately half" the farm wages paid elsewhere in the state.

Profits from illegal labor led to the kind of corruption that apparently worried Eisenhowe

r. Joseph White, a retired 21-year veteran of the Border Patrol, says that in the early 1950s, some senior US officials overseeing immigration enforcement "had friends among the ranchers," and agents "did not dare" arrest their illegal workers. Walt Edwards, who joined the Border Patrol in 1951, tells a similar story. He says: "When we caught illegal aliens on farms and ranches, the farmer or rancher would often call and complain [to officials in El Paso].
