There's absolutely no custom css needed for this and the job can be done with less code using native Bootstrap 4 classes alone:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/css/bootstrap.min.css" integrity="sha384-Zug+QiDoJOrZ5t4lssLdxGhVrurbmBWopoEl+M6BdEfwnCJZtKxi1KgxUyJq13dy" crossorigin="anonymous">
<section class="container">
<div class="row no-gutters">
<div class="col-sm-6">
<div class="row no-gutters">
<div class="col-12"><img src="img/image1.jpg"></div>
<div class="col-sm-6"><img src="img/image2.jpg"></div>
<div class="col-sm-6"><img src="img/image3.jpg"></div>
</div>
</div>
<div class="col-sm-6">
<div class="row no-gutters">
<div class="col-sm-6"><img src="img/image4.jpg"></div>
<div class="col-sm-6"><img src="img/image5.jpg"></div>
<div class="col"><img src="img/image6.jpg"></div>
</div>
</div>
</div>
</section>

Your markup is not matching as per your desired layout.It should be something like this :
<div class="box">
<div class="row">
<div class="col-sm-6 nopadding">
<div class="col-sm-12 nopadding">
<img src="img/image1.jpg">
</div>
<div class="row">
<div class="col-sm-6 nopadding">
<img src="img/image2.jpg">
</div>
<div class="col-sm-6 nopadding">
<img src="img/image3.jpg">
</div>
</div>
</div>
<div class="col-sm-6 nopadding">
<div class="col-sm-12 nopadding">
<img src="img/image4.jpg">
</div>
<div class="row">
<div class="col-sm-6 nopadding">
<img src="img/image5.jpg">
</div>
<div class="col-sm-6 nopadding">
<img src="img/image6.jpg">
</div>
</div>
</div>
</div>
</div>
Also add overflow:hidden in nopadding.
Hope it helps !

If you just swap around positioning and the wrappers, you should be able to get your desired effect
Also, you will have to take into account the paddings and widths you need as they will affect the positioning of the elements.
Demo works in full screen due to size
.gal-container {
display: block;
width: 600px;
padding: 16px;
}
.nopadding {
padding: 0 !important;
margin: 0 !important;
}
.box {
padding: 30px;
}
.row img {
max-width: 100%;
max-height: 100%;
}

<div class="gal-container">
<div class="row">
<div class="col-sm-6 nopadding">
<div class="col-sm-12 nopadding"> <img src="http://via.placeholder.com/300x150"> </div>
<div class="col-sm-6 nopadding"> <img src="http://via.placeholder.com/150x100"> </div>
<div class="col-sm-6 nopadding"> <img src="http://via.placeholder.com/150x100"> </div>
</div>
<div class="col-sm-6 nopadding">
<div class="col-sm-6 nopadding"> <img src="http://via.placeholder.com/150x100"> </div>
<div class="col-sm-6 nopadding"> <img src="http://via.placeholder.com/150x100"> </div>
