The events of Aug. 3 are outlined in the sworn affidavit of special agent Earl M. Kisler, who assisted in the Hammonds' arrest. On the day the fence was to be built, the crew and refuge officials arrived to find Hammond had parked his Caterpillar scraper squarely on the boundary line and disabled it, removing the battery and draining fuel lines. When a tow truck arrived to move it, Dwight Hammond showed up, leaped to the controls of the scraper and hit a lever that lowered the bucket, narrowly missing another special agent. Meanwhile, said Kisler, Steve Hammond shouted obscenities at federal officials. Neither Hammond resisted arrest.
"The refuge has been trying to work with Hammond for many years," said agency spokeswoman Susan Saul. A thick file at refuge headquarters reveals just how patient refuge managers have been. Hammond allegedly made death threats against previous managers in 1986 and 1988 and against Cameron, the current manager, in 1991 and again this year. Saul said Hammond has never given the required 24 hours' notice before moving his cows across the refuge and that he allowed the cows to linger for as long as three days, trespassing along streams and trampling young willows that refuge workers had planted to repair damage wrought by years of overgrazing.
