Translations for tacitly in French

Here are paragraphs from public domain books translated:

Parfois, surpris au milieu de ma tristesse par le regard inquiet de mon père, je lui tendais la main et je serrais la sienne comme pour lui demander tacitement pardon du mal que, malgré moi, je lui faisais.
