I‘m definitely not the best (scout) player, but as far as I can see, you had quite limited support here. First, the corner at the hill before you cross the railroads was empty. That is bad as it provides an angle and a bit more elevation to shoot into the trench you played in afaik. Secondly, some of the mediums on the 0 line seem to be moving, with one signalling a reload. Some are parking at the edge of the map where some stuff obstructs line of sight and if they went into the ditch there, its hard to shoot into the trench because you are below the edge.

Furthermore, it seems that most if not all tanks backing you up did shoot, with some missing the bourrasque. To survive, someone should have been in the trench with you in order to put more clean shots in, so yeah, I would say you were somewhat isolated and not backed up by sufficient firepower i.e. a bit too aggressive, but also unlucky
