"It was a dream, it was something I've been thinking about, but most importantly, just happy to help the team win," James told the BBC.
"We really, really had to fight for the win, and that's what we did," Wiegman told the BBC.
England had chances to increase their lead, including Alessia Russo's fierce shot in the 71st minute that sailed just wide.
"It did look serious, if you can't walk off the pitch it looks serious," Wiegman said of the injury to Walsh, who left the stadium on crutches.
Denmark, who beat China 1-0 to kick off their campaign, play Haiti the same day.
