Forum:Spurred to victory achievement

Ive tried twice for this achievement and wasted my time. now im raging and want to smash eveything. between pvp and this  ive wasted a whole week. whats the deal with this trophy. i have 745 hours into this game so i know what im doing but i used the advice  on this site and failed twice. i only need this achievement to unlock the platinum trophy. the only horse that died was on  the seth mission where we drive his wagon while he throws bodies out the back. according to this wiki it doesnt matter because i never hitched the horse. who ever edited that particular page  may be wrong or made a typo. i know i never hitched a horse other than my first one. never killed my horse either. completed 20 story missons again. the only horse that died was seths.
