More than $2.8 million in donations and commitments have flowed in to The Hole in the Wall Gang Camp in the week since a fast-moving fire destroyed four workshops at the Ashford retreat for children with serious illnesses founded by actor Paul Newman.

“The response has been overwhelming and comforting,” Ryan Thompson, the camp’s chief communications officer, said in an email Thursday. “We are deeply grateful. Gifts are still coming in, but as of this morning, we have seen more than 2,600 donations and commitments since Friday totaling more than $800,000. Absolutely extraordinary. This includes people who have sent in gifts on our website or through various fundraisers happening on social media as well as donations that are arriving by mail” in addition to corporate donations.

Among that total is a $125,000 commitment from the Aetna Foundation to match up to $125,000 in donations from CVS Health employees.

The $800,000-plus in donations are in addition to a $1 million pledge from the Newman’s Own Foundation and a commitment by Travelers to match up to $1 million in donations to rebuild the camp. Pro golfer Bubba Watson, a three-time winner of the Travelers Championship in Cromwell, pledged Thursday to make a $25,000 contribution toward the matching effort.

Thompson said no estimate was available Thursday as to what the cost to rebuild the camp would be but predicted it would be a “multimillion-dollar undertaking to build a fully accessible and inclusive facility that will meet the current, future and varied needs of the seriously ill children we serve.”

“That being said, with the match provided by Travelers and the Travelers Championship and the donations that it has inspired — in addition to the extraordinary donation yesterday from Newman’s Own Foundation above and beyond what the match will provide — we believe we are close to reaching the amount needed to build the facility that our campers and families need,” he said.

Thompson confirmed the damage was limited to the attached Arts & Crafts, Woodshop, Camp Store and Cooking Zone buildings and credited the “quick and brave actions” of local firefighters with preventing the blaze from spreading to the nearby dining hall and infirmary.

The cause of the fire remains under investigation but Ashford Fire Marshal Richard Whitehouse said this week it “doesn’t appear to be suspicious.”

An automatic fire alarm went off just before 5 p.m. Friday, and witnesses soon began calling in reports of a huge smoke column and flames.

No one was at the camp at the time of the fire and no one was injured, including firefighters battling both the flames and the icy conditions their hoses created.

Firefighters spent about 90 minutes containing and extinguishing the bulk of the fire.

Founded by Newman in 1988, the nonprofit camp has offered summer programs for thousands of seriously ill children each year. The old Western style campgrounds were inspired by Newman’s famed “Butch Cassidy and the Sundance Kid.”
