I see no name on the memorial from the photo. An object does not need to have a name in OSM, this is no Google maps. Instead you could have put the inscription text into the 'inscription' tag.

You cannot copy anything from Google maps as it is forbidden for OSM. Second, Google is a dump ground of random descriptions of objects put into names so it even is useless to copy anything from Google maps.

You must check the history of the objects in OSM you change. Here you would see that multiple people already tagged it that they do not know its name. A statue of a horse is a description or property of the object and can be described by proper tags (see e.g. https://wiki.openstreetmap.org/wiki/Key:statue), it is not its name. If there is indeed no name, there is a noname=yes tag for that.

Then I ask where does the name on https://www.openstreetmap.org/node/10936899407 come from?
