Hah! Glad to know I wasn't alone. I've triggered this twice now, immediately following the Strawberry - San Denis Dry Dash. First time, like everyone else here, they killed me and my horse (also a white Arabian I'd had from close to the start). I was also confused and pissed, but fortunately I had a save state from only maybe 30min before, so I loaded it, redid the run and rode to the same bridge, just north of the Stables. This time I jumped off the horse right before I reached the edge of the bridge, scoped on a figure sitting in the field and figured they were going to jump me again - seems like this is scripted for that bridge, and maybe immediately after the Strawberry - San Denis run. I started sprinting for the buildings on the right and managed to take cover before the gatling gun got me, and then was able to pick off each Leymoyne Raider one by one - I survived the ambush! Then I was curious if the gatling gun wagon was still around, and it was - and my character was able to jump on and use it. I'm currently taking it to Emerald Station to see if I can fence it, aside from that not sure what else I could do but maybe go and raid Shady Belle. Glad to see this wasn't a glitch and is in fact survivable, hope my story helps others - always save before leaving San Denis on that bridge!
